Opened for operational check. It's practically new, with very little storage time. The first stage switch only produces flashing lights. The second stage activates lights and starts dancing automatically to music. It feels like there are 5 or 6 songs included; I'm not sure of the exact number. It operates on three AA batteries. It hops, moves sideways, raises and lowers its arms, and its eyes blink.

The lights change and flicker to the rhythm of the music, making the effect of turning on the lights at night more pronounced.
