He is the side kick to Dora Márquez (lead character) and voiced by Danny Trejo.
Boots is athletic and energetic. He performs a series of acrobatic flips, somersaults, and cartwheels, along the way to their destination. His light weight also makes him easy to carry, even for Dora.
Unlike the animated series Boots gives a more style to a actual monkey. Removing his Boots seen in the animated series kept the movie to look more realistic which is what it was aimed for. Boots is mostly a gray-purple color. He has a yellow stomach and a pair of white eyes with greenish/black pupils.
He does make appearances in his boots but they don't appear later on possibly due to the fact he has grown out of them.
