Shifty Boo Mansion is a level of World 3 in Super Mario 3D World. It takes place in a ghost house. Its main features are the moving platforms. There is a harder version called Shiftier Boo Mansion that appears in World 11.
This level acts as the first Ghost House level of the game, so it wouldn't surprise you that Boos are everywhere in this level, as well as the Peepas from New Super Mario Bros. 2. Other spooky obstacles, like moving staircases and floating couches, also appear in this level as well.
- Green Star 1: After climbing the split staircase, there is a giant painting of a Boo on the wall. Jump into the Boo painting into a bonus room. Keep on following the rotation of the room to get the star, but watch out: the Peepa gang might get in your way!
- Green Star 2: In the second room, jump on the moving blocks to the left side of the room. Touch each portion of the bookcase on the left wall to reveal an alcove to the star.
- Green Star 3: By the last door that leads outside, go on the couch on the right to ride it on the platform above. Try to go in the fake warp pipe to reveal a star.
To the right of the Boo painting, jump on the couch and ride it to get the Boo stamp.
