A Sandile Gusher of Change is the third episode in Pokémon: Best Wishes (Pokémon: Black and White in America).
Ash now begins his new journey in Unova, accompanied by Iris (The new Misty/May/Dawn) and her Axew. During an argument, their old friend Oshawott appeared out of nowhere (whoa). Oshawott was happy to see Ash again since it followed them all the way out here and wanted to come along with them. Ash tried catching it but then he realized that Oshawott was the same one from Professor Juniper's lab. After retrieving it's pokeball from Professor Juniper, Oshawott disappears just as quickly as it appeard. Soon Ash and Iris fall into a hole which, according to a young boy named Dan, was caused by a Sandile and a whole group. What is the cause of the Sandile Uprising? And can Ash find Oshawott so he can come along with him? Yes.
