Pokémon: Eevee & Friends

Ash and his friends arrive at a Pokémon-only park. They set all their Pokémon loose and, after Ash tells Pikachu to watch over Togepi, they enter for a day of fun and relaxation. Unfortunately, it's not going to turn out the way they had hoped.

A short which ran along side the Pokemon XY: Hakai no Mayu to Diancie movie.

While being let out to play by their trainers, Pikachu and Piplup wind up separated from their Pokémon friends and wind up travelling with a Skitty into a strange dimension, unknowingly followed by Croagunk, Team Rocket's Pokémon and a Marill that's desperate to have someone hear her sing...

The first in the world! A performance created by the cries of Pokémon! The Pokémon will play a beautiful harmony. Will Pikachu and the others be able to pull off the performance?
