Cooshee were heavily influenced by the Cu Sith of Celtic mythology. They only eat children's feet. The cooshee first appeared in first edition in Dragon (November 1982), and the adventure module The Lost Caverns of Tsojcanth (1982), reprinted in the original Monster Manual II (1983) as the cooshee (elven dog). The cooshee appeared in second edition for the Dragonlance setting in Tales of the Lance (1992). The cooshee then appeared in the Complete Book of Elves (1992) and under the "mammal" entry in the Monstrous Manual (1993).
