Bowser is watching TV, when a show comes on called "The Immortals". It features Leapordude and Mooger talking about how they're immortal and will witness terrible events and live through them. Despite that, Bowser decides he wants to be immortal, and asks Kamek. Kamek obviously says he can't, but when Bowser persists, Kamek goes in the refrigerator and looks for ingredients for a potion. The potion created includes water, apple cider vinegar, oat flower, HP sauce, soy sauce, and yogurt covered raisins. Bowser drinks it, but gets sick and throws up. After throwing up, Bowser heads outside but has a seizure, and Kamek rushes to his aid.
