Through the wall (Super Mario 64)

Description
In Super Mario 64, go to Wet-Dry World. Go to the area with the Chuckya (the purple Bob-omb), and grab him. Walk to the corner, and touch the wall. Then, turn around, but DO NOT take a step away from the wall! After that, throw the Chuckya. You should slide through the wall and be outside of the course, in the water.
