Corporal Paraplonk

Corporal Paraplonk is a red Koopa Paratroopa that wears a bucket on its head and green shoes. He is one of Bowser's minions in Mario & Luigi: Bowser's Inside Story. He is first seen with Private Goomp and Sergeant Guy trying to take back Bowser's Castle from Fawful with a Banzai Bill Blaster. The minions however do not have any Banzai Bills, so Bowser goes into the castle to retrieve one. Once Bowser obtains the massive Bullet Bill, and gives it to his minions, they shoot the Bill into the castle.

Later, at the safe of the Tower of Yikk, Corporal Paraplonk and his companions watch as Bowser defeats Fawful Express. When Bowser opens the safe, the three push Bowser in, stating that Fawful put a good price for capturing Bowser.

The latest appearance of Corporal Paraplonk was right after the closing credits, where the minions ask Bowser for forgiveness of their treason. Bowser forgives them as long as they help with repairing the castle.

Trivia

 * Corporal Paraplonk is the only Koopa Paratroopa (aside from Parakarry) to wear a different color of shell than its shoes.
