was one of the "preview" Pokémon to the third generation of games, cards, and anime, having been released before the official release of the GBA versions.

The name Wailmer is derived from the words whale, wail, mer (the French word for sea), and possibly toddler, due to its playful, childlike demeanor. Its Japanese name, Hoeruko, is derived from the Japanese transliteration of the English word and the Japanese words for and . Unlike an actual whale, a Wailmer will spout water from its nose instead of a blowhole on its head. Wailmer will often land on beaches during sunny days and bounce around like a beach ball.

is a whale Pokémon, and the largest of all known Pokémon species. Living in the vast oceans of the Pokémon world, Wailord swims languorously in pods of about four members or more, often at the surface so it can breathe through its upper nostrils. With huge mouths these Pokémon can eat massive amounts of undersea food, such as krill, in a single gulp. When chasing somewhat larger prey, Wailord herd them by leaping out of the water and making humongous splashes in what is often described as a breathtaking display. If a Wailord inhales to the maximum capacity of its gigantic lungs, it is able to dive close to 10,000 feet below the surface. Optionally by puffing itself up, it can float high on the ocean surface or beach on a shoreline if it wishes. Despite being the largest Pokémon known, it's only the tenth heaviest.
