Ant Trooper Hill

Ant Trooper Hill, otherwise known as World 4-1, is the first course of World 4 in Super Mario 3D World. It is unlocked via completion of A Banquet with Hisstocrat, and its own completion unlocks Piranha Creeper Creek.

Layout
The level starts on a desert-like platform with some Ant Troopers nearby. Some nearby platforms can be used to enter a cave infested with Ant Troopers. When the player exits the cave, several rows of Horned Ant Troopers appear, with the Checkpoint Flag waiting beyond them. Some spiked grounds follow, which must be traversed via the Big Ant Troopers spawning from the nearby cave. A nearby pipe leads to an area with some Ant Troopers and the Goal Pole.
