Koopa Clogger

The Koopa Klogger is an invention of Kooky Von Koopa, that was seen in "7 Continents for 7 Koopas", an episode of The Adventures of Super Mario Bros. 3.

The Koopa Klogger is a satellite that can spawn large force fields within Warp Pipes everywhere, preventing anything from passing through them. When the Koopas flew to the Real World to take over all of the continents aboard the Doomship, Kooky made use of the device to keep Mario, Luigi, and Toad from following them.

Princess Toadstool was unintentionally kidnapped before the Koopa Klogger was activated, and while on board the Doomship, she tried to sneak past Bowser and turn it off. Although she was captured, she later managed to irritate a Bob-omb, and threw it at the Koopa Klogger to demolish it.

Upon doing so, the force fields were disable, and the Marios and Toad were then able to get into the Real World and stop all of the Koopalings.
