Squirrel is an enemy family from Final Fantasy Dimensions. Members of the family resemble a squirrel eating a round object, with the assumption of what the object is depending on the name of the enemy (e.g. nut, rock). They are based on the Nutkin et al enemies from Final Fantasy V.
In the Japanese version, members of the species either have the suffix "Eater" (イーター, Ītā?) or "Masher" (マッシャー, Masshā?). The translation refers to the nut enemies as "nutkins" in reference to the squirrel from Beatrix Potter's The Tale of Squirrel Nutkin.
