Treelo is a green and white lemur with a red nose, a white and blue tail, and blue hands, feet, eyelids, and ears. As a lemur, Treelo loves swinging from vines and other things and is very energetic. He also knows how to wiggle his ears. Treelo speaks in a unique trilling manner that sometimes becomes incoherent, especially when he gets excited.
