Kirby Squeak Squad, known as Kirby Mouse Attack in Europe and Kirby of the Stars: Calling on the Dorotche Gang (星のカービィ 参上! ドロッチェ団) in Japan, was beaten in 36:40.54 minutes by MUGG, by taking advantage of glitches and of the bottom screen, which is used to keep and mix the things Kirby swallowed during his adventure.
