|Species||Naked Old Person|
|Introduced in||"City of Thieves"|
|Latest appearance||"Holly Jolly Secrets Part II"|
Phil (also known as Pajama Ninja) first appears in the episode, "City of Thieves" when he steals the basket and glasses from the Cyclops. His pajamas are then stolen by Rock Wall Thief, and his glasses are stolen by a goblin. He is then punched by Jake. Phil wears a special pair of underpants that can lock, presumably so that they cannot be stolen.
He attends Finn and Jake's holiday event in "Holly Jolly Secrets Part II" and for the first time he was referred to by name as "Phil." It is unknown how Shelby knows his name. In the same episode, Phil wears a pair of puffy pants with Christmas Trees on them. He doesn't wear a sweater, but he wears a scarf.
MY MOST PRIVATE PARTS! PEEPED BY A BOY!
- His appearance is based on Phil Rynda, (former) Lead Character Designer on the Adventure Time staff. (That is why his face resembles a PHIL FACE, although the character Phil usually does not make the actual PHIL FACE expression, which involves and open mouth curled up at the corners and arched eyebrows.)
- Phil appears to look human; it's quite surprising that Finn did not notice this, considering he believes that he is the only human left in the Land of Ooo besides Susan Strong. Phil is more likely just a humanoid.
