Slip and Crash! A Mystery Pokémon?!

Aboard the Brave Olivine, Roy and Friede are in the middle of a battle when Fuecoco suddenly slips on a strange purple liquid on the floor. Then, Liko hears a mysterious crash come from another room, so the young Trainers investigate to find out who is responsible for the odd occurrences. After nightfall, they’re surprised to find the ship’s resident Pokémon gathered in the storage room, cheering as Shuckle battles a wild Polteageist who snuck onto the ship. When the battle ends, the Pokémon celebrate their new friendship, and Captain Pikachu formally invites Polteageist to join the crew!
