*[[Pokémon Mystery Dungeon: Gates to Infinity]]: Starmie runs the Sunken Treasure mini-game in [[Pokémon Paradise]]. In this mini-game, the player collects black, blue and red treasure chests by tilting their Nintendo 3DS.
[[Chinchou ]] and rocks appear as obstacles in this mini-game, and touching them deducts one treasure chest, starting with black chests. Unlike Treasure Boxes obtained from dungeons, they are opened upon obtaining. Starmie's mini-game can be played once every in-game day.
