Couple's Cake

Couple's Cake is an item found in Paper Mario: The Thousand-Year Door. The item is given to Mario after he completes the "Looking for a gal" trouble. Additionally, a Couple's Cake can be created by cooking a Snow Bunny with some Spicy Soup. This item has the same properties as a Slow Shroom, but always affects Mario's partner. It is interesting to note that, according to Wonky, Couple's Cakes remind Zess T. of her late husband and she is therefore apparently reluctant in making them; curiously, this situation is almost identical to Tayce T.'s quirk over Cake, which she similarly used to win her currently deceased husband over.

Later, it appears in Super Paper Mario, where Dyllis can cook it by mixing a Snow Bunny and a Berry Snow Bunny.
