Ramon

Ramon (a.k.a. "Rocko") is a high school student in Didi's class, he's very respectful of Mrs. Pickles as well as his mechanic teacher. He's a boy of few words, and mostly keeps quiet for a lot of the time. Although he looks tough to his other classmates, he's actually a very friendly, calm, cool-headed, and a good person who looks out for others. He's really popular with his black leather jacket, motorcycle boots, shades, and very neat hair. He makes his debut in "Little Dude", where he appears in the middle of class to change Tommy's dirty diaper (as he was late for class) to demonstrate how to change a diaper, after the other classmates did not want to. He befriended Tommy, because the latter reminded the former of his (Ramon's) little brother. Ramon tells Mrs. Pickles that changing Tommy's diaper wasn't a problem, because he's used to it with his little brother. Tommy is in awe of Ramon and greatly admires him. After he's lost by three of Didi's female pupils, Tommy's seen mostly trying to follow Ramon.

Besides riding a motorcycle, it's shown as Tommy follows him that he's learning how to be a mechanic. He takes great care of his hair and tries to stay out of trouble. However if someone starts trouble with him, he's not afraid to push back. Which is very evident, when the football player believes Ramon threw pudding on his shirt, which Tommy had really done by accident. He then proceeds to smear food on Ramon's clothes, to which Ramon responds by doing the same back to him and even stuffs a banana in his mouth. They both start a food fight in the school cafeteria, but both remain very quiet just standing and glaring at one another. However Ramon then finally speaks after the football player grabs Tommy and yells at him angrily, indicating he might hurt Tommy. After hearing Ramon speak, everyone stops. Ramon then approaches the football player, taking Tommy from him and carefully places him in his coat for protection.

He then takes Tommy out of the cafeteria, away from harm, and gives his say for the food fight to continue. To which the other students carry on the food fight, leaving another student in shock of what happened. He then returns Tommy to the girls, to which after Tommy takes off his sunglasses, he falls for the leader of the girls. He then leaves, calling Tommy by his nickname for him "Little Dude" to which Tommy returns his thumbs up gesture. Tommy seems to have picked up some things from Ramon, when Grandpa Lou asks "So, what did you learn in school today, Scout?". Tommy then immediately slings his food at Lou's face, who laughs, saying, "That boy's got an arm on him!". Tommy is seen smiling as he wears Ramon's glasses. Ramon returns for a brief cameo in Vacation as one of the audience members at the circus. In the latter episode, he dyed his hair black.
