Boots is a 5 (4 for the first 12 episodes) year old furry monkey and Dora's best friend. He's like a worshipful younger brother. Sweet and loving, he likes to hold Dora's hand. Unlike Dora, Boots sometimes makes wrong choices and gets discouraged. When he is feeling down, he always bounces back quickly with one of his flips. No one can make Dora laugh the way Boots can. He's the best friend you always wanted.
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. Without guidance from Dora, the viewer, or another character, Boots is quick to take his own, often dangerous or dead-ended, route. Dora often acts as the voice of reason. Boots also "loves" many things. In one episode, he would say many times "I love riddles. Call me 'Mr. Riddles'" or "I love nuts, I love chocolate, I love my ball, and I love, love, love...". Most importantly, however, Boots loves Dora and Dora loves him back, as both expressed verbally and physically in numerous episodes. He is disliked by many characters, and because of this, Caillou would often abuse him physically & emotionally.
Boots is mostly a gray-purple color. He has a yellow stomach and a pair of white eyes with black pupils. He is shown wearing a pair of red boots.
