The magazine "Cafe Guide" comes to "Cafe Lucky Cat", located on the first floor of the Butt Detective's office, for an interview, but the owner hurts his back, so Butt Detective takes over as owner for the day. The interview was going smoothly when a huge amount of sweet potatoes, eggs, fresh cream, and butter that the owner had mistakenly ordered arrived at the shop. Butt Detective and his team are surprised by the mountain of ingredients. In order not to waste the ingredients, Butt Detective decides to work with everyone in town to make a super-sized sweet potato.
