Basho

Basho is a ninja master "among other things" living in Old Japan on Red Dragon Island.

Role in Red Dragon Island
The Poptropican first meets Basho when they are looking for the ninja master so that he can learn from him and then save Jack and Annie. Basho pretends that he is not Basho and states that Basho was just at the store, buying eggs. So the Poptropican goes around town, helping others, and Basho secretly follows. When the player gets in trouble after beating The Yokozuna at the Sumo Wrestling Match, Basho comes in and saves the Poptropican from going to jail and tells the player to meet him at his house. The player goes to Basho's house and asks him questions, then Basho tells them that their training has begun.

Training
Basho takes the player to the Training Area, and there he helps instruct the Poptropican about the ninja skills they need. Then Basho tells them to meet at the wall next to his house for their last training mission. When the player goes there, Basho tells him to repair the wall, and when the player does and asks what ninja skills that taught them, Basho tells the player "No ninja skills, I just needed my wall fixed." The player is about to leave when Basho tells them to bring the Shogun to him, because they have some "unfinished business". The Poptropican tells him that they will, and sets off. After the player defeats the Red Dragon, Basho comes over to the player, Jack, Annie, and the Shogun, and reveals that the Shogun is his brother. Then Basho and the Shogun talk, forgive each other, and agree to help each other rebuild the city together. After that, the player teleports away.
