DP065: Sleight of Sand!

Plot
Still on the way to Veilstone, Ash and friends stop by a sand-pit to have some fun. All of a sudden, a Hippowdon from underneath it. Trouble appears when the over curious Pachirisu falls into its mouth. The situation worsens when two Team Rocket teams (Jessie, James and Meowth, and Butch and Cassidy) are also trying to catch Hippowdon.
