World 3 (Super Mario 3D World)

World 3 is the third world of Super Mario 3D World. It has a snow themed island and has ice blocks around the map. It lies on southwest of World 1, south of World 2, west of World 4, east of World 5, and below World 6, World Castle, and World Bowser. The world contains seven standard courses, a Captain Toad course, a Sprixie House, a Castle, and a Boss Arena. After the player have beaten Pom Pom, the blue Sprixie Princess will create a Clear Pipe to World 3-B, and clearing that level unlocks World 4.

Trivia

 * If the player glitch onto the Pipe on World Bowser, they'll fall onto this world. This claims that World 3 is under World Bowser.
