Chocolat's grandfather decides to come for a visit. Chocolat and the others quickly get annoyed by his crazy antics: stealing Chocolat's bed, showing up at school, turning the bathroom into a sauna, and dragging them out for all night parties. When Chocolat demands Grandpa leave, he challenges her to a heart-collecting contest. If she wins, he will return to the Magical World, but if she loses, he moves in permanently. Though Chocolat manages to capture a lot of hearts, Grandpa wins. He then admits the contest was just to get Chocolat more motivated about collecting hearts, bids them farewell, and heads back to the Magical World.
