Bob-Omb Battlefield: Die pinned to wall
Selecting any star but "Big Bob-omb on the summit" Enter the cannon next to you. Aim it as high and as far to the right as possible and fire. Repeat this and you will die in the air but with your feet on the wall of the course. You can also make it look as if your whole body is on the wall by going to the second cannon in the course. Aim the highest and most further right as possible and fire. Repeat and you will die on the ground but it will appear as though you were on the wall before the camera finds its proper angle.
