Koopa Clogger

The Koopa Klogger was a special satellite invented by Kooky Von Koopa, that could spawn large, spherical force fields within Warp Pipes everywhere, preventing anything from passing through them. The force fields were shown to be very powerful and nearly immobile.

The Koopa Klogger was controlled via a system of levers located aboard the Doomship. However, only authorized users, such as Kooky himself, were able to even touch the controls; an unauthorized user would instantly trigger an alarm upon contact, referred to by Bowser as an "Echo Goody-Good Warning Device".

In The Adventures of Super Mario Bros. 3 episode "7 Continents for 7 Koopas", the Koopas had flown to the Real World aboard the Doomship, where Bowser assigned his seven Koopalings to each take over one of the Real World's seven continents. Knowing full well that the Mario Bros. would follow them to the Real World in an attempt to stop them, Bowser order Kooky to activate the Koopa Klogger. Before the Doomship had left the Mushroom Kingdom, Princess Toadstool was unintentionally sucked up into the Doomship through its Super Slurp Pipe, prompting Mario, Luigi, and Toad into chasing after the Doomship. However, just before the trio could fly through the Warp Pipe that the Doomship went through with Raccoon Power, the Koopa Klogger had been activated, creating a force field in the Warp Pipe that caused the three of them to lose their Raccoon Power upon touching it.

With the Koopa Klogger active, Mario, Luigi and Toad were unable to enter the Real World, thus allowing the Koopalings to freely take over the continents. Princess Toadstool attempted to sneak over to the controls, but she set off the alarm, and was wrapped up in the chain of a Chain Chomp. Back in the Mushroom Kingdom, Mario, Luigi and Toad tried to pull the force field out of the pipe using a giant plunger, but were unsuccessful.

Later on, Princess Toadstool managed to irritate a Bob-omb by teasing it, which set off its fuse. The Chain Chomp and Paragoombas guarding Princess Toadstool all fled from the active Bob-omb, while the Princess quickly grabbed it and ran up to where the Koopa Klogger was. The Bob-omb blew up upon hitting the Koopa Klogger, demolishing it. Upon doing so, the force fields were disabled. Marios and Toad were then able to get into the Real World, where they were able to help Princess Toadstool reclaim the continents from the Koopalings.
