After climbing through an open window of a home in Vail, Colo. last week, a large black bear checked out the living room, then tried his paws at playing the piano.

It was a short music lesson. According to security camera footage, the four-legged trespasser spent more time messing up the house while the homeowner was away last Wednesday, Channel 2 TV reported.

By the time the owner got home, the bear had gone back out the window.

The woman initially thought vandals had broken into the house. Police found minor damage, including food missing from the freezer, the station reported.

The homeowner solved the mystery when she watched the camera footage.
