What are breeding anomalies?
Breeding anomalies, shortened to BAs and previously known as breeding mutations (BMs), are anomalies that can randomly occur when breeding two boucles together. They most often modify the boucles body in some way or another. There are common, uncommon, rare and legendary BAs.
Are BAs optional?
Most BAs are optional if rolled randomly! However, BAs are never optional if inherited from a parent. In the list below, the name of the BA is followed by * if it is not optional when rolled randomly. If it is also followed by +, the BA can occur on imports!
Are BAs inheritable?
BAs are inheritable, but at a lesser rate than genes. If only one parent has the BA, it will pass at a 25% rate. If both parents have the same BA, it will pass at a 50% rate. However, some BAs can only be expressed on certain mane types and thus will only express if the foal also has that mane type. All inherited BAs are not optional.
How often do BAs roll randomly?
Alternate Birthstones (I & II), have a 20% chance each to appear at any foal, regardless of if the foal has other BAs rolled or not (as long as those BAs are not incompatible with alternate birthstones, for example void).
For all other BAs, there’s a 2.5% chance that the foal will have a rare or legendary BA, a 7.5% chance that the foal will have an uncommon BA and a 15% chance that the foal will have a common BA. A foal can randomly roll 0-2 BAs, but can inherit more!
Can I choose the BAs?
On an import, you can choose Alternate Stone I or Alternate Stone II and one of the following BAs:
- Chimerism
- Brindle
- Reverse Brindle
- Bend-or Spots
- Birdcatcher Spots
- Lacing
On foals, you can use the 400MP/Enchanter Reward to add two BAs of your choice, and you can use as many Enchanter Rewards as you like on one foal!
Can you have all the BAs?
It is possible to add multiple BAs with the Enchanter Reward, however not all BAs are compatible. Eg You cannot have multiple types of ears, multiple types of wing, multiple types of tail etc.
Common Breeding Anomalies
Alternate Birthstones I & Alternate Birthstone II: +
These common BAs change the birthstone from the month’s common birthstone to one of its less common alternate stones:
Dual Stones:

A common BA, dual stones creates the appearance of two different gems within the bouclite. The gemstones will be the current month’s birthstone and the next month after it. If the boucle also has Alternate Birthstone I or Alternate Birthstone II, all birthstones will be from that set. If combined with Double Horns, each horn can look like its own type of gemstone! However, the appearance in the eyes and hooves are always split.
Trial Stones:

A common BA, trial stones creates the appearance of three different gems within the bouclite. The gemstones will be the current month’s birthstone and the next two months after it. If the boucle also has Alternate Birthstone I or Alternate Birthstone II, all birthstones will be from that set. If combined with Triple Horns, each horn can look like its own type of gemstone! However, the appearance in the eyes and hooves are always split.
Uncommon Breeding Anomalies
Excessive Hair Growth (Excessive Poodaleere and Excessive Lion’s Mane)*:
Excessive Hair Growth is an uncommon BA that causes the mane of the Poodaleere and Lion’s Mane types to cover a larger portion of the body! It changes the mane type of Poodaleere to Excessive Poodaleere and Lion’s Mane to Excessive Lion’s mane. Once the BA is applied, it inherits like any other mane type and does not need to be written in as a BA in the reference nor in breedings! You can add Excessive Hair Growth to any geno with the Poodaleere or Lion’s Mane type.
*Excessive Hair Growth is not optional when inherited or rolled!
Elf Ears:

This uncommon BA replaces the ears with extra pointy elf ears! These boucles typically have better hearing than most!
Feather Wings:

This uncommon BA causes feathery wings to sprout from the boucle’s withers, similar to those found in birds! They sometimes grow big and strong enough for the boucle to fly, but are assisted better with air magic. They adopt the colour of the main body or mane unless the boucle has plumes or other mutations that colour the body.
Finback:

This uncommon BA causes a ridge along the spine similar to a fish’s dorsal fin. The fin can be any colour and may vary in height and transparency.
Gemini:

Gemini is an uncommon BA that causes the foal to be born with two heads! It is up to you if they act and think independently or in connection! Each head will have the same BAs unless affected by Corruption or Ancients’ Blessing. Each head can be affected differently by mutations!
Rare Breeding Anomalies
Albinism*:

Albinism is a rare BA that turns the coat white and the bouclite a pastel pink, pastel purple or pastel blue. Sometimes, markings can show through very, very faintly in an off-white colour.
*This BA is not optional when randomly rolled!
Bobtail:

This rare BA shortens the tail of the boucle to between 3-12 inches (7-30cm). It may or may not have long tail hair and look just like a normal horse tail or look similar to other bobtails like deer, bears and rabbits. These boucles do not seem to have any balance issues, just like lapins. (Bobtail lines are not included in the foal line templates so you can customise the appearance!)
Chimerism*: +

Chimerism causes two foals to fuse together in utero, causing one individual with two genotypes! The edges between the genotypes will be sharp, and each area will show its own genotype. Either genotype have an equal chance of passing its genes to the offspring.
*This BA is not optional when randomly rolled.
Double Bat Wings:

This rare BA causes two pairs of leathery wings to sprout from the boucle’s withers, similar to those found in bats! They sometimes grow big and strong enough for the boucle to fly. They take on the colour of the boucles base coat. Even though there are two wings, they count as one BA!
Double Betta Wings:

This rare BA causes two pairs of flowing fishy wings to sprout from the boucle’s shoulders and down the upper legs, similar to the fins of betta fish! Despite being called ‘wings’ they never give the boucle the ability to fly though they might swim a bit faster! The fins may be any colour. Even though there are two wings, they count as one BA!
Double Butterfly Wings:

This rare BA causes two sets of butterfly wings to sprout from the boucle’s withers! They are not quite strong enough to help a boucle do more than glide, but combined with air magic they can fly properly! The wings can be any shape and colour. Even though there are two wings, they count as one BA!
Double Dragonfly Wings:

This rare BA causes two sets of see-through wings to sprout from the boucle’s withers, similar to those found in dragonflies! They can be any colour. They are not quite strong enough to help a boucle do more than jump a bit higher, but combined with air magic they can fly properly! Even though there are two wings, they count as one BA!
Double Feather Wings:

This rare BA causes two sets of feathery wings to sprout from the boucle’s withers, similar to those found in birds! They sometimes grow big and strong enough for the boucle to fly. They adopt the colour of the main body or mane unless the boucle has plumes or other mutations that colour the body. Even though there are two wings, they count as one BA!
Geode:

This is a rare BA that causes crystals of bouclite that extend from the horn and hooves of the boucle.
True Kirin*: +

A rare BA that only occurs in boucles with the Kirin mane, True Kirin causes a tine-like horn and cloven hooves! It does not affect the colour of the bouclite. You CAN add True Kirin to Kirin foals using Enchanter/400MP rewards.
This BA is not optional when randomly rolled, and has a higher chance of occuring in boucles with the draco mutation!
Legendary Breeding Anomalies
Dinocorn:
This legendary BA is actually four BAs in one! It has a random chance to be rolled for any mane type, and adds Double Nubbin, Crest, Dino Feet and Dino Tail (if the boucle doesn’t already have them). You CANNOT add Dinocorn to a foal with an Enchanter/400MP reward, but you can use multiple ones to add all of the BAs that make it up. Dinocorn has the same chance as other BAs to be inherited.

Doge:
This legendary BA is actually four BAs in one! It has a random chance to be rolled for Poodaleere and Excessive Poodaleere mane types, and adds Floppy Ears, Brindle, Paws and Excessive Hair Growth (if the boucle doesn’t already have them). You CANNOT add Doge to a foal with an Enchanter/400MP reward, but you can use multiple ones to add all of the BAs that make it up. Doge has the same chance as other BAs to be inherited.

Fluttercorn:
This legendary BA is actually two BAs in one! It has a random chance to be rolled on foals with the nectar mutation, and adds Butterfly Wings and Antenne (if the boucle doesn’t already have them). You CANNOT add Fluttecorn to a foal with an Enchanter/400MP reward, but you can use multiple ones to add all of the BAs that make it up. Fluttercorn has the same chance as other BAs to be inherited.

Mericorn:
This legendary BA is actually three BAs in one! It has a random chance to be rolled for any mane type, and adds Double Fin Ears, Narwhal Horn and Mertail (if the boucle doesn’t already have them). You CANNOT add Mericorn to a foal with an Enchanter/400MP reward, but you can use multiple ones to add all of the BAs that make it up. Mericorn has the same chance as other BAs to be inherited.
Boucles with the Orca mutation have a higher chance to randomly roll this BA!

Vulture:
This legendary BA is actually five BAs in one! It has a random chance to be rolled for the Bald type, and adds Beak, Feather Ears, Feather Wings, Feathered Neck and Talons (if the boucle doesn’t already have them). You CANNOT add Vulture to a foal with an Enchanter/400MP reward, but you can use multiple ones to add all of the BAs that make it up. Vulture has the same chance as other BAs to be inherited.
