BW22 - "A Venipede Stampede!"
Admiring the scenery of Castelia City, Ash and his friends meet Burgh, the Castelia Gym Leader. Burgh tells them that Ash's gym battle will have to wait as Bug type Pokémon in the city have been restless and that it is a sign of danger to come! Travelling down into the sewers, they find a Venipede that has been injured in its rush to the city. Why was Venipede in such a rush, and what does this mean for Castelia City and the other Bug type Pokémon in the area?
