Turbo-bashable doors

Turbo-bashable doors are double doors rarely found throughout Super Mario Sunshine. Although Mario is normally unable to break through them, this is easily accomplished by starting up a super dash with the Turbo Nozzle from a fair distance in front of the gates. This is the objective of the Turbo Dash! mission in Delfino Plaza. The bell tower in the southwest corner of the plaza has Turbo-bashable doors Mario must break through to retrieve a Shine Sprite within the tower.

The police station also has Turbo-bashable doors in front of it. Mario must charge up at a good distance in front of them and crash through the doors to enter a bonus area where the Turbo Nozzle is tested.

Turbo-bashable doors are imbedded in one of the platforms near the shore and the lighthouse. To break through them, Mario must begin dashing across the water and crash through the doors to receive a hidden blue coin.

Two Turbo-bashable doors make up the small structure within Delfino Airstrip. Mario is intended to return here later in the game and break through the building to find a blue coin concealed in a block of ice.

Notably, there is a lengthy glitch involving these doors in the airstrip. The player must complete Bianco Hills and unlock the Turbo Nozzle, all the while without saving the game. They must then die with zero extra lives, get a game over and restart the game. This allows the player to use the Turbo Nozzle when they first enter the airstrip. Although it can be used in this area, touching, or even dashing toward, the Turbo-bashable doors here causes the game to crash.
