Episode appearances[]
In "Recycled Koopa," after Mario, Luigi, Toad and Princess Toadstool clear out the garbage dumped into Mushroom Castle, they believe the Koopa Troop will reattempt it, at which point Toad brings out Luigi's Plumber's Periscope in a cardboard box and gives it to Mario to spy on the Koopalings and Bowser in order to find out. With the Plumber's Periscope, Mario looks into a nearby Warp Pipe and notices that Bully, Kootie Pie and Big Mouth Koopa are employing Sledge Brothers to dump garbage through a Warp Pipe leading to another land. In response, Mario and Luigi jump through the Warp Pipe to King Koopa's Castle, planning to put an end to the Koopalings and their pollution.
