Boots the Monkey, whom Dora met one day in the forest, is her best friend. He is friendly and enthusiastic, and usually wears nothing but his beloved red boots, hence his name. He is blue with a yellow stomach. His parents look similar, with variations in eyes, height, clothing, and fur.
Boots is present with Dora on most of her adventures, and he helps her solve clues and puzzles. He also loves baseball and is on Dora's team. He enjoys riding Rojo the fire truck.
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 "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 expressed verbally and physically in numerous episodes. His devotion and love always has Boots more than willing to drop whatever he is doing at the moment for Dora. For her sake, he has even engaged in adventures on his own, assisted by the viewers.
Boots' vocabulary is limited but steadily increasing. Dora teaches him Spanish through memorable songs and phrases.
Boots was voiced by Harrison Chad in the original English version and then, from season five onwards, by Regan Mizrahi.
Boots reappeared as a cameo in The Dora To Evolution! during a flashback Dora mentions Ash that Boots would be fine. His full appearance debut was at Monkey Business! where he and his Aipom needed help with a Pansage who had injured its arm.
