Odoru Pokémon Himitsu Kichi

Having seen all 6 shorts, this one has nothing but the pokemon dancing around while wrecking a building. All shorts are listed on IMDb except the 5th Camp Pikachu.

There are 2 pokemon groups, Pikachu's and Meowth's, who chase each other around while not dancing.

Meowth has a stick which causes all the pokemon to dance. The buttons on the stick have different song speeds which make the pokemon dance differently.

The only story here is rescuing some pokemon in a cage. As in all the other shorts there was a lot more happening with the pokemon working together.

Gotta Dance is all the pokemon do in this short.
