The Osohe Dance (sometimes referred to as the Wess Dance by fans) is a dance used in Mother 3 used to open three doors throughout the game. The first two are in second floor and basement of the Osohe Castle respectively, and the final door appears in the Murasaki Forest, preventing access to Doria's house. The two in Osohe Castle appear as a giant face with a mouth that opens, while the Murasaki Forest door simply slides into the ground after a successful performance of the dance. The only two characters seen performing this dance are Wess and Salsa, the latter having to learn all three parts of the dance by studying the symbols on the wall; Wess reveals that Kumatora and Duster have the ability to perform the dance, but are never seen doing so.
Before Wess does the Osohe Dance, the song Open Sesame Oil! plays, which becomes Open Sesame Tofu! as the dance begins. Similarly, Salsa has Dance! play before he begins and Laugh! Be Happy! during the dance, but he has a third track called What Happened?! that plays instead if Salsa does the dance incorrectly, resulting in Fassad berating and promptly shocking him at the door in the Osohe Castle basement. Wess only opens the door in the second floor of Osohe Castle; Salsa opens the other two.
