Mutations

Excuse the mess...

This article is currently in development. We'll post on the main page when it's complete. Check back later!

Mutations are a rare mix-up in a wolf's genetics that make them more unique! Not all wolves have mutations, but those that do may be more valuable or more visually distinct than other wolves.

Wolvden's mutations system is elaborate and varying! There are multiple different types of mutations, each obtained through different means, and even an ability for mutations to stack.

Mutation Basics

Mutation Basics

There are multiple aspects of a wolf's mutation status that can be complex to understand, but we will break each part down here!

You can find details about a wolf's mutations, if any, under the Looks section of their profile page. Here, you'll find a Mutation section, a Secondary Mutation section, and a Carrier Status section. Mutation and Secondary Mutation provide information on mutations that wolf actively possesses, while Carrier Status informs about mutations a wolf has the capability of generating through breeding.

Mutations and Secondary Mutations

Mutations and Secondary Mutations

Each wolf has two slots available for mutations, the Mutation and Secondary Mutation slots. This means that a wolf could have two mutations simultaneously! However, not all mutations can be doubled up.

Mutations are defined specifically as a "Mutation" or "Secondary Mutation", specifying which slot it will take up. Large, lineart-changing mutations like Brachycephaly are most frequently in the "Mutation" slot. Meanwhile, mutations that have more of a layering effect or have no visible effect, like Albinism or Deafness, will take up the "Secondary Mutation" slot. There is no current scenario where a mutation will be able to take up the slot that it is not typically assigned to.

A wolf cannot have two "Secondary Mutations" or two "Mutations" at the same time. For example, you will never have a wolf with Polycephaly and Sirenomelia, as these both take up the "Mutation" slot. Similarly, you will not have a wolf that simultaneously has two types of Piebald, since all Piebald mutations are "Secondary Mutations".

Any two mutations that fill the Mutation and Secondary Mutation slots separately can be doubled up, just not two that would share the same categorization! So, you could have a Brachycephalic wolf with Melanism, a Polycephalic wolf with Deafness, or many other combinations!

From the list below, you can pair any "Mutation" or "Secondary Mutation" together, and that combination is possible on a wolf in-game!

Mutation Categories
Mutations
Brachycephaly
Conjoined Twins
Polycephaly
Polymelia
Sirenomelia
Secondary Mutations
Albinism
All Patches
All Piebalds
Deafness
Hereditary Cataracts
Melanism
Spontaneous Blindness

Carrier Status

Carrier Status

Another value informing of a wolf's mutation status is Carrier Status. This trait relates to Genetic Mutations, mutations that can be passed from parents through recessive genes. We'll discuss this type of mutation further down on this page.

In order to reveal a wolf's carrier status, one must pay for the wolf to be analyzed at Gene's Hollow. Here, Gene will take Silver Cones in exchange for revealing if a wolf is a carrier for any of the four current genetic mutations. After it's been revealed by Gene, the wolf's Carrier Report will be updated to reflect the results.

If a wolf has never been carrier tested for any mutation, their Carrier Status will display as "Unknown" with a link to Gene's Hollow. Otherwise, you will be able to select View Report to view the wolf's status for each genetic mutation.

In a wolf's carrier report, you'll find four possible statuses for each mutation. If a wolf has a genetic mutation, they are not considered a carrier, but they will still have the ability to pass the mutation to pups.

Icon	Meaning
	The wolf has not been carrier tested for this mutation
	The wolf has been tested and is NOT a carrier for this mutation
	The wolf has been tested and IS a carrier for this mutation
	This wolf has this mutation

You can learn more about genetic mutations, carriers, and recessive genes in the Genetic Mutations section of this page.

Customization

Customization

Got a wolf with a mutation, but find them a bit lack-luster? Don't fret-mutated wolves can be customized with no consequence!

When you load a wolf with a mutation into the Wolf Customizer, their mutation will not appear. This does not mean that it's being removed, however! After you hit the Customize button, their new look will be applied and their mutation will be completed untouched. So, if you load a wolf with Albinism, you'll be customizing their look underneath their Albinism, and they'll still have the mutation after the customization has been applied.

Wolves with mutations can also have any applicator applied without harming their mutation.

Types of Mutations

Types of Mutations

Mutations can be assigned four different categories depending on their method of obtention and effect on the wolf.

Random mutations are mutations that appear randomly in any breeding, without any prerequisite.

Genetic mutations are passed through recessive genes, and parents must have the gene or mutation for their pup to get the mutation.

Applicator mutations can be applied to any wolf using an applicator, and pups can only get the mutation if their parent has it.

Finally lethal mutations can be random or genetic, and are characterized by causing a pup's death before they can reach adolescence. The lethal categorization is secondary on top of the mutation being random or genetic.

When a wolf has a mutation, you will be able to view that mutation's categories on the wolf's page under the Mutation or Secondary Mutation fields. Each category will display a different icon.

Icon	Meaning
	This is a random chance mutation
	This is a recessive genetic mutation
	This is an applicator mutation
	This is a lethal mutation

We will go into detail on each type of mutation below!

Random Mutations

Random Mutations

Some mutations have the chance to show up randomly in any breeding. The chance, however, is very very low! You could breed hundreds or even thousands of pups and not run into a random mutation!

There are some ways to increase your chance of getting a random mutation. The mother having a lower fertility will provide a small boost, as per the unique quest The Next Generation. Additionally, you may opt to use a Wolf Meat item, purchasable during the Halloween event. This item will provide a higher chance for a puppy in the wolf's next litter to have a random mutation.

There are currently six possible random mutations, listed below.

Random Mutations
Conjoined Twins
Deafness
Polycephaly
Polymelia
Sirenomelia
Spontaneous Blindness

Genetic Mutations

Genetic Mutations

Genetic mutations are produced by hidden genes present in some wolves, called carriers. Hidden genes are always recessive, meaning that both parents must have the hidden gene for a chance for a puppy to develop the mutation. Since you can't see hidden genes from the outside, the only ways to know if your wolf is a carrier of a hidden gene is by gene-testing them at Gene's Hollow or breeding them to another carrier.

Hidden genes originate from newly-generated wolves like wolves befriended in explore or created from scratch in the Customizer. Newly-rolled lead wolves, new befriended wolves, and new customized wolves have a very small chance of carrying one of the four possible hidden genes. If you have a wolf you're particularly attached to, however, who you'd love to have produce a genetic mutation, you may choose to use a Wolf Blood item, purchased during the Halloween event! A wolf given a Wolf Blood before breeding has a chance of producing a pup with a recessive genetic mutation in their next litter, even if neither parent is a carrier of that mutation! This would also allow a wolf that's a carrier of one mutation to birth a wolf who's a carrier of a different mutation.

Wolves are able to be a carrier of multiple hidden genes at the same time. So, you could breed a line of wolves who carry every hidden gene in the game! The genes are treated as completely separate traits, so they will not interact with each other in any way while breeding.

When breeding a wolf with a hidden gene, there is a small chance that they will pass that gene onto their pup, even if the pup does not get the mutation itself. It's not a guarantee, however, for the gene to pass on. Every genetic mutation has the same pass rates, that we'll list below.

Genetic Mutation Pass Rates
Non-carrier x Non-carrier	100% Non-carrier
Carrier x Non-carrier	90% Non-carrier, 10% Carrier
Mutation x Non-carrier	85% Non-carrier, 15% Carrier, 0% Mutation
Carrier x Carrier	80% Non-carrier, 10% Carrier, 10% Mutation
Mutation x Carrier	70% Non-carrier, 15% Carrier, 15% Mutation
Mutation x Mutation	70% Non-carrier, 20% Mutation, 10% Carrier

There are currently four possible genetic mutations, listed below.

Genetic Mutations
Albinism
Brachycephaly
Hereditary Cataracts
Melanism

Applicator Mutations

Applicator Mutations

Applicator mutations are mutations which can be obtained by applying them directly to your wolf using a Mutie on Demand applicator.

Mutie on Demand applicators are obtained during the Black Friday/Cyber Monday Promotion with any $50 purchase or higher. They can be used to apply a specific applicator mutation to a wolf of your choosing who does not already have a secondary mutation.

Besides being applied using applicators, Applicator mutations also have a small chance of being passed to pups through breeding. These are not genetic/recessive mutations. Applicator mutations cannot be carried or passed as recessive genes through generations. A pup will only have a chance of getting an applicator mutation from their parent is if one of their parents has the exact mutation. Though similar, Patches and Piebald mutations cannot pass any other mutation besides their specific shape.

There are currently six possible applicator mutations, listed below.

Genetic Mutations
Patches: Mottled
Patches: Split
Piebald: Biewer
Piebald: Frontal
Piebald: Torn
Piebald: Uneven

Lethal Mutations

Lethal Mutations

Lethal mutations are mutations which will cause your wolf's death after a certain number of rollovers. These mutations are visible from birth and will kill before your wolf reaches adolescence. Lethal mutations could be genetic or random.

When a pup in your pack is born with a lethal deformity, you will receive a message in your daily rollover summary about an "Unusual Puppy". This will describe what is wrong with the pup. Over the course of the next few rollovers, you will receive additional messages detailing the pup's daily life.

If you leave a pup with a lethal mutation alone, they will die! Luckily, there are a couple methods for keeping the wolf in your pack for longer.

If you like the pup's genetics other than their mutation, you can purchase an Osha from Raccoon Wares for 500 Silver Cones. This item will remove the chosen wolf's mutation while retaining all of their other genetics. If the wolf has both a mutation and secondary mutation, it will remove the mutation first.

Since most lethal mutations are very rare, many players will be inclined to preserve any they get. You can keep a pup with a lethal mutation in your pack using a Jellyfish to immortalize your wolf. Jellyfish can be purchased from the Grove for 10 Gold Cones. Be sure to get the normal Jellyfish item and not the Translucent Jellyfish item, as these have two different effects!

In order to use a Jellyfish to immortalize your lethal mutation, you must have a spare Immortal Slot. You must pay Gold Cones to purchase immortal slots, with the first slot costing 10 GC and each subsequent slot adding 10 GC to the previous price.

Once you have a Jellyfish and an empty immortal slot, make sure that your pup isn't being protected by a pupsitter, and then use the Jellyfish from your Hoard! This will turn your wolf immortal, which will apply a few effects. The wolf will never age, and it will never be able to breed or perform a role. Essentially, it will act as a decoration in your pack! Once you've immortalized a wolf, there is no way to undo the action besides retiring the wolf, so act carefully!

There are currently five possible lethal mutations, listed below alongside how they are obtained.

Rollover Messages
Birth	Birth Message New Puppy was born with an anomaly. All puppies have short snouts and big heads, but this particular pup is very wrinkled and visually deformed, as though someone pushed his face into his head. New Puppy is audibly gasping for air, but he is alive, and he seems healthy for now. 1/2 Month Old New Puppy's breathing is laboured. Her tongue barely fits within her shortened mouth. She makes lots of gasping and snorting noises every day. New Puppy's eyes opened earlier than your other puppies, and they seem to prolapse a bit. 1 Month Old New Puppy is having serious issues with breathing. There's not a quiet day in your den -- the puppy's snoring and snorting is a constant, worrisome noise. Death Message (1.5 Months) Unfortunately, New Puppy passed away due to complications with breathing. Every breath he took was just not enough to fill his tiny body with enough air. It seems eerily quiet within your den after the puppy's snorts stopped forever.

Birth	Birth Message You were ready to rejoice the rare birth of twins, until a dreadful realisation overcame your joy -- you notice the puppies are joined at the hip. New Puppies seems eager to suckle milk nonetheless, so you embrace them in a loving snuggle. 1 Month Old You learn how New Puppies functions as they learn the world themselves. They interact with each other, they cuddle together, they try to get away from each other... But their fate is to be joined forever. They seem to be pooping a little more than ordinary puppies. You wonder if they're not able to control that part of their body. 2.5 Months Old New Puppies is learning how to walk without falling and tripping. You explain the basics of teamwork to them, and they seem to understand you. A minute later, the puppies bite each other's paws. Ah, parenthood. 3.5 Months Old When it's time to try solid foods, New Puppies are struggling to properly digest their portions. You often see small pools of vomit around your den. 4 Months Old New Puppies are not able to process solid foods without whining in pain and vomiting. They also cannot control their bowel movements, and their stool is often covered in blood. Death Message (4.5 Months) Sadly, New Puppies have passed away due to problems with their digestive system.
