Ep 13. Sleight of Sand!

Ash and friends are making their way through a desert and stumble upon a circus in the middle of nowhere. The circus performers, including a group of acrobats and a magician named Lily, invite the group to stay and watch their show. During the performance, Lily's Skitty goes missing, and it's up to Ash and his friends to help her find it.

As they search the circus grounds, they discover that the Sandshrew and Sandslash that live in the area have been causing trouble for the circus. With some clever thinking and teamwork, Ash and his friends are able to locate the missing Skitty and stop the Sandshrew and Sandslash from ruining the circus's big finale.

In the end, Lily thanks the group for their help and invites them to join the circus as performers. Though they decline, they leave with newfound appreciation for the hard work and dedication it takes to put on a show and entertain others.
