Joshua's dungeon

Joshua's Dungeon is the Dungeon that Joshua made for Finn and Jake (Finn specifically, so he can get strong without him) to explore in the episode "Dad's Dungeon." The entrance to the dungeon appears to be guarded by a Dumb Rock so that no one else but Finn and Jake can find it. It is full of traps and Monsters. At the end of the dungeon, Jake's Family Sword is there for Finn and Jake to obtain.
