Hammer is extremely shy. When King Koopa comes back to take Lakitieu, Hammer jumps in the way and gets caught instead. He takes Hammer as a prisoner, wanting to trade Lakiteu for him. His brothers come to save him, but Bowser Jr. made Boomer stay back. Hammer frees himself, but now he's lost; and being chased. Can the Bros and Bowser Jr. find him and take him back? Or will King Koopa succeed at last?
