Mr. Game and Watch's semi-permanent turtle
From Glitches
From the game Super Smash Bros. Melee for the Nintendo Gamecube
This glitch may not work depending on the version of Super Smash Bros. Melee you own
Play as Mr. Game and Watch and go to the Mushroom Kingdom, Green Greens, or Icicle Mountain. Now, try breaking lots of blocks with the turtle (back+A in the air). Jump keep trying to break blocks from different angles (like below you and above you) and eventually you'll land with the turtle still in your hands. You can run around with it and use some attacks with it. Sometimes it will go away. But, if you have it out and die, you'll still have it out when you come back to life.
