Pokémon Play²O is a handheld game released by Dynatech in 2005 which allows electronic water games to be played. The device has electronic sounds, an electronic timer, and pivoting water jets. The goal is to guide Pokémon which are encased in plastic balls into the Poké Ball by using the water jets before the timer reaches zero. A Wailmer and Sharpedo act as obstacles, while a Lotad, Horsea, Spheal, and Mudkip are the Pokémon being guided. It requires 2 AAA batteries to operate.
