Go through the Great Fox

From Glitches

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

Go to the Corneria level as Mr. Game and Watch. Now, go under the Great Fox to the guns. Stand under the thinnest part of the neck of the ship. Do a small jump (tap X or Y), then a normal jump, and at the peak of your jump, do the B+up attack. If done correctly, Mr. Game and Watch will go through the ship.
