When Frank goes to the Afterlife to bring Dade back to Earth to help in the effort against Evil Dade, Dade initially refuses as he doesn't want to lose his Fruit Snacks. Frank and Dade fight, ending with Dade regurgitating Fruit Snacks into Frank's mouth. Frank decides not to try and take Dade anymore and leaves. After a while, Dade comes to the realisation that helping Frank will result in him receiving more Fruit Snacks, so leaves the Afterlife to assist him. When Dade returns, he tosses a single Fruit Snack at Evil Dade, instantly killing him. Afterwards, Dade accidentally trips on the floor and lands on a lone Fruit Snack, accidentally killing himself.
Fruit Snacks are incredibly powerful, eliminating Evil Dade, an immensely powerful being, with just one packet.
