Pods of Mewmer can be detected from many miles away by their rapid, laughter-like sonar calls. They use their psychic powers to detect approaching ships and dart deep underwater to hide if they think people are trying to find them.

While this Pokémon usually lives in the sea, it can survive on land, although not too long. A Mewmer is said to possess the genes of all Pokémon.
