Pokemon: Pikachu no Natsuyasumi

Both are incredibly high-octane short films tied to a movie, starring animal-like creatures doing all sorts of hijinks. 

Both 『Pokémon Concierge』 & 『Pikachu's Summer Vacation』 revolve around Pokémon in a resort style setting and allowing them to rest and enjoy their vacation to their fullest. And of course; it entails many interesting interactions between other pokémon as they play and socialise with each other. The only differences is that humans are more involved in Pokémon Concierge which adds and extra level of depth in the storytelling. If you enjoy an Iyashikei genre type Pokémon shows, these shows will do.
