The Rival Trio
From the Super Mario Wiki
Captain Goomba, Captain Shy Guy, and the assisting Lakitu run into the Elite Trio and notice that they share the same goal of finding Bowser. Private Goomp accuses Captain Goomba of copyright infringement, and the Goomba Squad is forced to fight each member. After the battle, the three of them bicker over their leadership skills, prompting Captain Goomba to make his leave.
