The Grotto Key is a key item that appears in Paper Mario: The Thousand-Year Door.


The Grotto Key is found in the storeroom of the Pirate's Grotto on an upper ledge. In order to get to it, Mario must first have either Koops or Bobbery activate the switch from a distance and then stand on the wooden lift and ride it up. Mario then can jump onto the barrels to get to the Grotto Key which unlocks a door leading further into the Grotto.
