This hat has three charges. While holding the hat you can use one action to expend one of its charges and speak a command word that summons your choice of a bat, a frog, or a rat. The summoned creature—who magically appears in the hat—tries to get away from you as quickly as possible. The creature’s neither friendly nor hostile, and it is not under your control. It behaves as an ordinary creature of its kind, and disappears after one hour.
