"Chocolate Boy" (Real name unknown) is a fictional character in the Hey Arnold! TV Series.
If there's chocolate around, it won't be around for long as long as he's in the area. How Chocolate Boy got his craving for chocolate dates back to when he was a kid. His parents forbade him to eat chocolate, but his nanny secretly gave him some. When Chocolate Boy's nanny had to go away, Chocolate Boy was upset, so he went into his room and ate chocolate, a lot of chocolate. He admits this to Arnold, who quickly consoles him. Chocolate Boy's nanny wanted him to behave and be happy. He then swore to give chocolate up at the end of the episode "Chocolate Boy", and now has a newfound addiction to radishes.
He appears in Anime: Evolution, Warkol reprising his role where he is known as Radish Boy and has an opposite version of him in the underworld who is deemed as Chocolate Boy.
