Koopa trash, also named Koopa's garbage or Koopa garbage, is an object in the The Adventures of Super Mario Bros. 3 episode "Recycled Koopa."
Description[]
The Koopa trash is left behind in Brooklyn by King Koopa and the Koopa Kids. The Koopa trash is somehow capable of transforming whoever touches it into a Koopa Zombie or even other animals into Koopa's minions, as shown from seagulls becoming Paragoombas and fish becoming Spiny Cheep-Cheeps. Koopa trash even turns statues into reasonable facsimiles of King Koopa himself, such as the Statue of Liberty into the "Statue of Kooperty."

"Recycled Koopa"[]
After King Koopa demands the Koopa Kids to clean up the garbage from his castle, they send it to the Mushroom Castle garden through a Warp Pipe. Mario, Luigi, Toad, and Princess Toadstool go to King Koopa's castle and steal Hip's magic wand and use it to send the garbage back, taking the wand with it in the process.
Back at the Mushroom Castle, Mario uses Luigi's Plumber's Periscope and notices several Sledge Brothers dumping the garbage down another Warp Pipe leading to another world and decide to follow the garbage's path. They hide in the trash boxes and get thrown down the pipe, leading down to Brooklyn, which is covered in the Koopa trash. Mario and Luigi witness the citizens of Brooklyn mutating into Koopa Zombies and attempt to clean up the garbage.
When the Koopa Kids bring the powers the garbage has on the Real World to King Koopa's attention, he brings his Doom Ship to the Real World and dumps more trash to mutate the rest of New York City. King Koopa has further plans to do this all over the Real World and uses the mutated victims to use as ammunition against the brothers. It is after Mario begins to mutate into a Koopa Zombie himself that he and Luigi decide magic is not working to clear out the garbage, so they build a machine known as the Trash Smasher to clean it up.
As King Koopa continues dumping more Koopa trash onto New York City with his Crud Cannon, a stray pile from the cannon lands on Mario, finishing his mutation shortly after he and Luigi are finishing the Trash Smasher. With the Trash Smasher, Luigi successfully cleans up all the trash, restoring Mario and the entire city back to normal. King Koopa tries to dump more Koopa trash, but Mario and Luigi adjust the Trash Smasher so that it is capable of flight and fly it close enough to the Doom Ship to suck up the garbage before it reaches the ground. King Koopa's plan is thwarted, and Mario and Luigi chase him out of the city.
