Horror Time (Adventure Time episode)

Horror Time With Finny Krueger and Jakenstein is a Halloween episode of Adventure Time. In it, Finn and Jake are telling scary stories. Jake tells "The Shmowing", Finn tells "A Nightmare In The Candy Kingdom", and then Marceline shows up just in time to tell "Draculene". The episode has been censored in the UK for its gore and scary themes.
