3x10 - Cardcaptor Sakura

Sakura's school is hosting a bazaar, and Kero attends to eat sweets, hiding in the woods. Nakuru, meanwhile, brings Spinel Sun along and hides him in the same forest while she attends the bazaar. Kero meets Suppie (the pet name Nakuru gave him) but is completely oblivious to his true nature and befriends him, forcing him to eat some of the sweets. As a result, Suppie becomes intoxicated by the sugar and goes on an eating binge throughout the school. Kero, who is unable to explain the predicament to Sakura, asks her to use the Sleep card on all the customers, allowing him to get rid of Suppie.
