Terrifying sound for a field mouse

HOOT

A nocturnal hunter’s call that sends small creatures scurrying for cover.

A "hoot" is the eerie call of an owl, which would be a terrifying sound for a small field mouse since owls are natural predators. The clue plays on the idea of fear by linking the mouse’s perspective to the owl’s distinctive noise. It’s a straightforward definition with a touch of imagery—no hidden wordplay, just a vivid scenario.
