Crud Cannon

The Crud Cannon is a weapon owned and presumably built by King Koopa. The cannon's purpose is to launch garbage over vast distances.

In The Adventures of Super Mario Bros. 3 episode "Recycled Koopa", Koopa, wanting to mutate all of New York City, let alone the entire human race, including Mario, into Koopa Zombies and other creatures into his minions (e.g. seagulls into Paragoombas and fish into Spiny Cheep-Cheeps) through exposure to his garbage, employs the use of the Crud Cannon to do so from the safety of his Doomship. After Luigi cleans all of Brooklyn with their Trash Smasher, turning the borough's populace and Mario back to their original forms, he and Mario modify the Trash Smasher to make it flight capable and chase and scare Koopa and his Crud Cannon out of the city.
