Tiffany Oiler makes his debut in the episode "My Two Favorite People." Tiffany was called on by Jake to make Finn and Lady Rainicorn jealous. He is obsessed with being Jake's best friend, and also knows how to play a viola. He fought with Finn fiercely, but ran away whining when Finn spat on him. He vowed to have Jake as his best friend. He is also one of the members of Jake's old gang alongside Jake, Gareth, and the Flying Lettuce Brothers. It is explained that he and Jake are old friends, and he obsessively waits for Jake to contact him to hang out again. He tends to speak in long, nonsensical "threatening" monologues belied by his youthful voice.
Tiffany deeply longs for Jake to ditch Finn and be his best friend again, so they can be master criminals together, as explained in "Dentist." In the episode, he and Finn are partnered by ants to take down some worms threatening the ant colony that provides dental services for people in Ooo (Tiffany has lost most of his teeth after eating the Baker's Shard he and Jake's old gang stole in "One Last Job."). He develops a grudging respect for Finn, but cannot bring himself to save him when Finn is in danger of falling into a worm's maw, though he does decide against stabbing the helpless Finn, as was his first plan. He winds up falling into the worm's mouth himself and is reported as "missing in action" by the ants, though his ultimate fate is unknown. The episode also reveals his last name to be "Oiler."
Tiffany wears a pink shirt, blue shorts, blue socks, and brown shoes. He has a blond mullet. He also has a peach-fuzz mustache on his face. His skin is a pale aquamarine and he is short, with a size and build comparable to that of an elementary school child. He carries a hidden knife in his shirt.
