Pokémon: Pikachu and Pichu

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.

Pikachu and some of the other Pokémon camp out in the woods and help the Pichu brothers get on the train.

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...

Pikachu and the other pokemon play a game of hide and seek.
