Ant Trooper Hill is the first level of World 4 in Super Mario 3D World.
- Green Star 1: In Cat form, climb the wall near the exit of the tunnel to get the star.
- Green Star 2: After the checkpoint, jump on the Big Ant Trooper to ride it towards an alcove with a Warp Pipe in it. In the hidden area, climb the wall in Cat form or use the Ant Troopers to jump up there.
- Green Star 3: In the second Big Ant Trooper section, jump on the Big Ant Trooper to ride it towards the star. Just jump up to it while under it.
In the end of the first tunnel, try to approach it from the right jump on one of the Ant Troopers leading towards the Ant Troop Stamp.
