This probably works in many areas where "auto-slide" hills intersect walls. But, here's an example. Go behind Grunty's Lair and then jump over to where the auto-slide hill intersects Grunty's Lair. You'll try to slide down, but you'll hit the wall, so you won't be able to go down. Banjo will slowly drift away from the Lair, but if you keep the control stick slightly tilted up, Banjo will just lie there, with dust pouring out of him. It looks like he's steaming.
