The Bullet Bull Express is the final level of World 3 in Super Mario 3D World.
Unlike most other levels, The Bullet Bill Express features two trains that can both be accessed.
The Green Stars
- Green Star 1: From the very start, move fast towards the star before it goes offscreen. You can use the ? Blocks to help.
- Green Star 2: Destroy the Goomba Tower with Cat Bullet Bills to get the star.
- Green Star 3: By the Warp Pipe in between crates, go in it to go on the other train. On that train, destroy the crate with Toad in it whom reward you with a star.
