Eevee & Friends (Japanese: Pikachu and Eievui Friends) is the Pikachu short that debuted a few months after the 16th movie.
Pikachu, Oshawott, Pansage and Axew are playing in tall grass. They then fall down a hill, and they hear a voice. The group splits up and tries to find the Pokémon. Pikachu briefly sees it a few times, but can't locate it. Then, something covers his eyes. Pikachu turns around and meets Sylveon, the new Eevee evolution. Oshawott, Axew and Pansage arrive, and as usual, Oshawott falls for Sylveon. The Pokémon then leads its new friends to the Eevee House, its home. Eevee is called for and slides down a grassy terrain, but falls on top of Axew. Sylveon helps the two up, and Eevee is introduced to the others.
As Oshawott finishes greeting Eevee, he is electrocuted by a Jolteon who runs out and hugs him. Sylveon takes off Jolteon, only to leave a fainted Oshawott. Eevee, Axew and Jolteon play tag and run inside the Eevee House. Oshawott is left behind, running after them. Knowing he will cause trouble, Pikachu, Sylveon and Pansage run after him. The playing Pokémon enter Glaceon's room, with ice shards to jump over. They play in the sculpture, while Oshawott breaks through the ice instead of hopping on it. Glaceon, seeing this, becomes mad and uses Sheer Cold on Oshawott.
Oshawott, frozen, falls out of the room and makes a perfect item for Eevee, Jolteon and Axew to land on as they exit. He breaks out of the ice and, as usual, goes on the wild goose chase. Next, the three hop around Leafeon's room, a tent-like home hanging from a vine. Oshawott gets stuck in some vines and swings the entire nest around, making everyone dizzy. Leafeon, angry, uses Leaf Storm, making Oshawott appear as a leafy shrub.
