Big Sky, Small Fry! - S20.E33

With no class today, Ash and Lana go fishing, but they may end up catching more than they bargained for since the lagoon they're fishing in may contain a water-type Totem Pokémon. If there is, then Lana is determined to battle it. Meanwhile, Kiawe takes the rest of the gang to visit his family's dairy farm, and Team Rocket doesn't seem to be having much luck with their own fishing.
