Continuing to Nimbasa City, Ash and friends suddenly find themselves caught in the rain. They notice a mansion nearby and go inside hoping to seek shelter from the rain. However, things are not as they seem. Soon a group of Litwick begin tormenting them and cause havoc.

On the way to Nimbasa City, Ash meets a Pokémon trainer and the two decide to battle. During the battle Oshawott's scalchop is kicked away from Oshawott and becomes lost in the woods. Devastated, Oshawott frantically searches for it, and eventually a replacement for it.
