The Tile Pool is a location in Super Paper Mario. It is found in Chapter 3, where Francis has stolen Tippi. The Tile Pool is a water level and contains many enemies such as Cheep-Cheeps and Bloopers. Here you find Thudley the Pixl. At the end of this subchapter, you must fight a Giant Blooper called Big Blooper.
In early screenshots of the game, Tippi was seen used in the Big Blooper fight. However, in the final game, Tippi has been kidnapped and it is impossible to fight the Big Blooper with Tippi.
There were also early screenshots of this level showing an unused Pixl.
