Violet Elephant Lola is very, very shy. She's also the strongest Jellybeanie in the world of Chroma! Just no loud noises, please: a startled elephant could lead to some squished feet. And that's not good for anybody!
Obviously, don't nominate any human characters. Hybrids like Cheetah or The Lizard are okay, as are shapeshifters with one set animal form (eg Professor McGonagall.)
