None Shall Pass is an anthropomorphic giant sign who lives in the Ice Kingdom. It does not let anyone pass by it unless one helps it with its poetry writer's block. Finn and Jake help it by saying words and short phrases that rhyme with "butt."
- This character is possibly a reference to Gandalf's quote from The Lord of the Rings, "You Shall Not Pass!"
- This quote was also said by the Ugly Monster in "Dad's Dungeon."
