Corporal Paraplonk

Corporal Paraplonk is a red Koopa Paratroopa who wears green shoes and a bucket on his head. He is one of Bowser's minions in Mario & Luigi: Bowser's Inside Story. He is first seen with Private Goomp and Sergeant Guy in Dimble Wood. He, Bowser, Goomp, and Guy launch a Banzai Bill at Bowser's Castle, which was occupied by Fawful.

Later, at the safe underneath Bowser's Castle, Corporal Paraplonk and his companions watch as Bowser defeats Fawful Express. When Bowser opens the safe, the three push Bowser in, stating that they are defecting because Fawful would give the three more rations.

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.
