Private Goomp

Private Goomp is a Goomba who wears blue pajamas, and a minion of Bowser in Mario & Luigi: Bowser's Inside Story. He is first seen with Corporal Paraplonk and Sergeant Guy trying to take back Bowser's Castle with a Banzai Bill Blaster. However, they don't have ammo, leaving their king to get some. When Bowser acquires a Banzai Bill, his three underlings fire it into the castle.

Later, Bowser runs into Private Goomp wandering around alone outside Tower of Yikk. In talking with Private Goomp, Bowser learns that one of the three Star Cures is stored in a vault beneath his own castle. Bowser hastily leaves for said vault without Private Goomp.

At the vault, Private Goomp returns with his former companions, watching as Bowser defeats the Fawful Express, and as Mario and Luigi repair Bowser's memory of the combination. Once he opens the safe, however, the three quickly push him inside, stating that Fawful has placed a reward on Bowser's head. This same safe is later found in Peach's Castle.

Private Goomp's last appearance comes after the closing credits of the game. Private Goomp and his two companions visit Bowser, who is bedridden after a fight with the Mario bros. They apologize for their treason and asking to rejoin the Koopa Troop. Bowser pardons them on the condition that they help with repairs on his Castle.
