The 'Koopa-Doopa-Raiser-Upper' device, newly implemented by King Koopa, sends the Mushroom Kingdom up into the clouds and creates an awesome challenge for Mario and his friends. Everyone and everything is floating up to Koopa's domain. // Koopa and his Koopalings invade the real world in the Doom Ship, sealing all the warp pipes behind them and leaving the Mario Brothers unable to interfere! King Koopa gives each Koopa Kid a continent to terrorize, and imprisons Princess Toadstool, accidentally sucked aboard before they left. Air Date: Nov 17, 1990
