Penthouse of Horror - S1.E15

Fin, Reef, Lo and Broseph get trapped in an old hotel room that Bummer claims to be haunted by a young couple who died there a month before. The gang doesn't really believe in hauntings, that's until the ghost shows up. But Fin still tries to convince the groms that ghosts aren't real. Meanwhile, the Kahuna faces off against an undead fish stick that he accidentally brought to life. At the end of the episode it is clear that Reef likes Fin.
