1x8 - Pokémon Journeys

Satoshi and Go meet a Pochama from the Sinnoh region that has run (actually swam) away from its owner Misaki. Traveling to Sinnoh to return it, they learn that Pochama ran away because of its jealousy toward Misaki's Gureggru, who is competing with Pochama for her attention. The two Pokemon decide to settle their quarrel by competing in the Pokémon Drift Ice Race, which Satoshi and Go decide to enter as well.
