When did they suddenly get to a desert?
Nitpicking aside I really liked this episode, what I especially loved was that they remembered that Ash actually has more than one Pokemon and they gave many characters and Pokemon unique roles suited to each of them. Goomy's the center of the episode, but Clemont got to use his brains, Frogadier shows off his power, Dedenne gets to battle and even Chespin gets to do something useful all the while doing his usual comedy routine.
