Carlos Ramon is the Latino-American class clown, always making a pun or joke about whatever situation the class is in. He is a hands-on learner, preferring to invent unique devices, such as a best-loved stuffed animal, an instrument or rain catcher, rather than learn from a book like Dorothy Ann. Carlos tries to be funny by telling several jokes, but they often backfire and cause the kids to groan "Carlos!" in an aggravated manner. By contrast, Ms. Frizzle seems to enjoy his jokes, sometimes even complimenting him on being observant in the process of making them up. He is kind and outgoing, but he can have a bossy side as well. Despite this, Carlos is good-hearted and has a brotherly instinct about him. In "The Magic School Bus Going Batty", his father also makes puns, to which the other kids' parents would respond, "Mr. Ramon!" also in unison. In the episode called "Get Ready, Set, Dough", Carlos has the responsibility of making chocolate cake for Ms. Frizzle's birthday.
