Episode Description: A wild Polteageist stows aboard the Brave Olivine, leaving behind puddles of purple liquid found by the crew. While Liko and Roy investigate the source of the liquid, Polteageist makes itself known to the ship's other Pokémon when it challenges their Shuckle out of jealousy over its berry juice. Liko and Roy eventually find the ship's Pokémon hosting a private match between Polteageist and Shuckle to welcome Polteageist aboard the Brave Olivine, and decide not to intrude. The next morning, Friede nonchalantly accepts Polteageist, while Diana is delighted to find Polteageist has turned her teacup into a Sinistea, revealing they had already known about Polteageist's presence and let Liko and Roy discover it by themselves.
