BW 013 "Chillarmy is a Neat Freak!?"
Satoshi and his friends continue on their journey to Shippou City. Suddenly, they run into a girl named Bel who was sent by Araragi-Hakase to deliver a badge case to Satoshi. Her parcel got dirty inside her bag, but Satoshi is happy just to be getting a badge case in the first place. When Satoshi hands the badge case back over to Bel to show her his Tri Badge, it disappears! At that time, a "chinchilla pokemon," Chillarmy, is seen running away with the badge case in its mouth! Satoshi and his friends hurry after Chillarmy. Will Satoshi be able to get his badge case back?
