Mus are rather weak enemies, encountered around the South Figaro and Nikeah areas. The Peeper enemies, fought in the World of Ruin on the Solitary Island, are also extremely weak, and die without having to do anything. The slightly stronger Knotty, fought in Yeti's Cave, are only mere nuisances, as they can inflict Imp on a party member, but are also rather weak. However, Mus have a very powerful Rage called Snare, which instantly kills an enemy monster, but fails on enemies immune to instant death and those that float; on the plus side, it works on undead enemies.
