KAra, twice actualy. Her original Yoshi self and her avian chocobo self. this came about as a silly idea, I wanted to see kara turned into a chocobo so there you go. I think she ate something she wasn't supposed to and it turned her into the chocobo.
This is the only pic of her as a Chocobo I have. someday I hope I can get a better one.
