Clear Pipe Cruise

Clear Pipe Cruise, otherwise known as World 6-1, is the first course in World 6 in Super Mario 3D World. It is unlocked via completing King Ka-thunk's Castle, and its own completion unlocks Spooky Seasick Wreck. This level also appears as the fourth course of the Bonus Episode in Captain Toad: Treasure Tracker.

Layout
The level starts on a set of platforms with some Fire Piranha Plants, Mines, and Clear Pipes nearby, followed by a Warp Box which transports the player to the next area. After avoiding some enemies, the player reaches the Checkpoint Flag. A nearby Clear Pipe takes the player to an upwards slope filled with Clear Pipes with Fuzzies in them. A Warp Box and a Piranha Plant infested area follows, allowing the player to reach an area where five Key Coins need to be collected in order to progress. The last Warp Box of the level transports the player to an area with Captain Toad and the Goal Pole.
