Rare/Mythical animals?

[PinkGregory]

I think my one may have already been done, but it didn't look like what I'm suggesting.

Also would be innaresting to use this idea as a jumping off point for others.

Basically it's like exceedingly rare versions of animals, in my case, the Jackalope (horned rabbit.) (alright, more horned than usual!)

A rare rabbit that can be fed into the science machine for a research bonus.
