How DoorMouse joined the Tourney
Just as DoorMouse was opening up his new school, DoorMouse University, he received a letter from Nintendo saying that a tournament is being held at Nintendo Land. He raced from UmiCity to Nintendo Land, and signed up for the Smash Bros. Tourney. The manager told DoorMouse that Miyabi Kagurazaki was waiting for him at the end of the Tourney. DoorMouse was enraged that Team Umizoomi is after the gold trophy as well, so he aligned forces with Raoh and Jagi to defeat Team Umizoomi once and for all.
