Chet appeared in the episode "Slumber Party Panic." He almost figured out that the Candy Zombies were among the Candy People, who were all having a slumber party in Princess Bubblegum's castle. He heard them and freaked out and was about to explode when Finn turned the volume up on the radio, which calmed him down. He is also seen arguing with Peppermint Butler over who gets to be "Grill-meister" in the episode "The Real You."
Chet resembles a bon-bon and speaks with a surfer accent. He seems to be easily disturbed, since he became very uncomfortable when Tree Trunks and Mr. Pig were with each other in "Dream of Love." He is voiced by Dee Bradley Baker.
Um, does anyone else hear that?
I hear something I don't understand, and it makes me scared!
