Egbert, Yoko, and Shelly are three baby Tyrannosaurus from Ice Age: Dawn of the Dinosaurs, consisting of two males (Egbert and Yoko), and one female (Shelly).
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.)
