Ah yes.. The true nightmare in Dream Land. To start a map with this copy ability, use code 02004B50 77 (note there is a colon before the 77 and this code is an internal code, so typically only works on an emulator). Enjoy ^^. Unfortunately lots of glitch copy abilities completely freeze the game.
The icon of 0x77 is ファイヤー (Fire in Japanese). Whenever I used 0x77, I'd either just get a game freeze or it would force the game to reset, but the glitchy animations while Kirby is moving and the pause screen map corruption glitch makes it stand out.
It also froze the game after clearing the first level.
