Wailmer is a spherical whale Pokémon with no tail. It has a dark blue topside and a tan underbelly with grooves. It has two fins that have finger-like appendages, baleen plates that resemble teeth, and a pair of nostrils on the top of its head functioning as blowholes.
Wailmer stores water inside its body, which it expels through its nostrils to startle people. When storing water in its body, it can turn into a bouncing ball. The more water filling its body, the higher it can bounce. It becomes lethargic when it is dry. It swims with its mouth open and eats tons of food a day, such as Wishiwashi. It lives in the sea, and can only live on land for a short amount of time. It occasionally bounces onto the beaches to play. On rare occasions, pods can be seen washed up on shore — a result of genetic memories of having once lived on land. Dhelmise and Sharpedo are natural predators to Wailmer, and Cetoddle is thought to be its close relative.
Pokémon Channel: On the beach, the player can fish for Pokémon with the fishing rod and bait provided. Wailmer is uncommon, but if the player reels Wailmer to the shore, the player can see the tremendous size difference between Wailmer and Pikachu.
Pokémon Ranger: Shadows of Almia: Wailmer was seen in the 12th and 13th mission, being caught by the Team Dim Sun for their cargo ship. They were supposed to take Wailord, but they tried to bluff their way through by calling Wailmer a Wailord Mini.

Wailmer can survive on land for a time, but it loses vitality if its body dries out, so it tends to stay in the sea. Apparently it likes to startle other Pokémon, as you can see from all the pranks it plays!
In Island Time, a Wailmer befriended Robin and eventually evolved into a Wailord in order to transport him, Ash, and his friends to a ship heading to Ever Grande City. However, Robin later decided that he wanted to go back to the island he was living on.
In Leading a Stray!, a Wailmer was trapped in the sewers, but it was rescued by Ash, who later helped it rejoin its family in the ocean. It evolved into a Wailord in the same episode.
This might be the cause of a glitch that freezes the game if the player is surfing on a Wailmer and it evolves after a battle caused by a Rod.
Despite being found as an overworld spawn in Frigid Sea, Wailmer is not in the Crown Tundra Pokédex. It is the only Pokémon that can be found through random encounters in the Crown Tundra to not appear in this Pokédex.
