Backstreet Bustle

Backstreet Bustle, otherwise known as World 5-3, is the third course in World 5 from Super Mario 3D World. The level is unlocked by clearing Sunshine Seaside, and its own completion unlocks Chargin' Chuck Blockade Is Back. The level is blocked by a Bowser statue which can be removed with 80 Green Stars. It appears to be the shortest level in the game.

Layout
The level starts in an underground area with a platform that requires two characters to move. A nearby Double Cherry in a Question Block can help with that requirement. After players avoid some Goombas and a Fire Piranha, they await before another one of the aforementioned platforms. It requires three characters to move. This platform transports players to an area with two Lava Bubbles and the Goal Pole.
