Paging Pennywise.

A knife-waving thief wearing a creepy clown mask robbed a store in Colorado in a scene fit for the horror flick “It,” stunning footage shows.

The costumed crook — who sports wild orange hair, a round nose and an evil smile — brandished a blade with a purple handle as he strolled into JR’s County Store in Pueblo around 7 a.m. Monday, according to surveillance footage posted by CBS Denver.

The masked menace shook the knife at a teller, demanded cash — and made off with an undisclosed amount, according to police, who are hunting for the culprit.

The creep is likely a heavy-set male, who was wearing a dark jacket, blue jeans and black Nike shoes, according to the Pueblo Police Department, which is seeking tips about the crime.

In the 2017 movie “It,” based on the classic Stephen King novel, Pennywise the Dancing Clown terrorizes the fictional town of Derry.
