In Science Class, Kamek taught the students how to set off a volcano experiment, instructing each of them to add baking soda. Peach and Daisy managed to successfully complete the experiment, but some of the other students had trouble. Luigi added a small amount of baking soda to his volcano, but he panicked and ran off when he worried it might explode (although it only managed to bubble a little). Mario just shoved the entire box of baking soda into his volcano and called it a success. Bowser ignored the experiment altogether and instead pranked Toad by sprinkling baking soda over his nose while he was sleeping. Wario inhaled the baking soda through his nose and started hallucinating as if the baking soda was a drug. Fishy Boopkins added his baking soda, but his volcano refused to erupt. He decided to add several more boxes to the mixture, which caused a massive explosion that sent Boopkins flying out of the building.
