Fall through Icicle Mountain

From Glitches

From the game Super Smash Bros. Melee for the Nintendo Gamecube

Go to Icicle Mountain as Kirby, with another character. Make both of them stand under an ice block. Now, make Kirby grab the character and throw the character up. You will both hit the ice and then fall through the course. You'll both die. Strangely, the many floors underneath don't stop you. This doesn't happen without the ice block.
