Maushold

Maushold (イッカネズミ) is a Normal-type Pokémon introduced in Generation IX of the Pokémon series. It evolves from Tandemaus and has two forms: Family of Four and Family of Three, with the Family of Four being much more common (99% chance) than the Family of Three (1% chance). Maushold resembles its pre-evolution, Tandemaus, but with the addition of smaller mouse members. They live together in large nests, with separate rooms for different purposes, such as eating and sleeping. The exact relationship between them is unknown, though the larger members protect the smaller ones in battle and they will all fight together against strong opponents. Maushold is the only known Pokémon that can learn the move Population Bomb. Maushold debuted in Pokémon Scarlet and Violet and was added to Pokémon GO on July 17, 2024. In Japanese, it is known as イッカネズミ (Ikkanezumi).
