In the main AU, Violet has a pet named Presto, who is just an ordinary rabbit. However, in Icicle's World, they are a musician who can't trust anyone, unless they know enough about the other person in order to be friends with them.

This is what they look like. Their eye colour automatically changes based on how they feel, but their eye colour is mainly light-grey.

I was originally going to create a different character (that is also a rabbit), but then I remembered that Violet (one of my characters) has a pet rabbit.
