Mutation Fails
*Disclaimer. I don't know coding on this site so I am not sure whether or not this is even possible but it's still an idea. I'd love to hear feedback and at least whether or not its even possible. Mutations on this site are random so I kinda have an idea that this might not be a very likely thing.

Okay, so i was doing a bit of thinking about mutations and how they work and came up with an idea thats pretty, out there.
Mutation fails.

So, basically, when breeding a mutation (certain ones) they actually can produce mutation fails? This would be rare (Maybe only possible when using a item similar to lion scrotums?) maybe we could even get exclusive mutations from these fails? Mutations we can't get any other way that is.

EXAMPLE : Primal
Produces -> Primal: Fails -> A mane mutation (fems.), overgrown teeth, bobbed tail.
Exclusive fail EX: Trufted fur (M/F)

EXAMPLE 2 : Piebald (Any)
Produces : Piebald: Fails -> Blind, Achromia.
Exclusive fail EX: Deaf(M/F)

Overall Example:
Now, lets say this was possible, we'd need an item that might be responsible for these fails.
Maybe something like Lion Heart.
It would go something like this.
"Chance of passing mutation: 30%. Chance of mutation fail: 20%"
This is just an example. The numbers would/could be adjusted. This would be a one time use and could be fed to females or males.

Overview
- I dont know if this is actually doable.
- An item is fed to a lion or lioness and gives you the opportunity to pass a mutation, fail mutation, or even an exclusive mutation to a cub(s).
- Exclusive mutations could only be obtained by this item (and by breeding certain muties too it)

I'd love to hear questions. Concerns. or comments.
