Surfer Boy

Surfer Boy is a surfer from "Sun, Surf, and Science". Mandark believed that he was Dee Dee's boyfriend due to her fawning over all the cool things he did, which made Mandark jealous of him and he wanted to become cool like he was in order to win over Dee Dee. Mandark then entered a surfing competition, believing that the Surfer Boy would be in it, but instead it turned out to be Dee Dee. After sacrificing himself to save Dee Dee and losing the race, Mandark started drowning and was saved by the Surfer Boy. As thanks, Mandark offered him use of his Indoor Wave Pool and the two became friends.

In the episode he is referred to only as “Surfer boy”, and his actual name is never revealed.

He was voiced by Tom Kenny.
