Runs on two "D" batteries. When switched on, the microphone lights up, the monkey wildly plays the guitar which creates real guitar string sounds, he sways side to side, his head moves up and down, he sings "squeaks", his right foot taps to the beat and the bell on his hat rings. I've included a video in the photos section.There are a few standard scratches on the tin, particularly around where the battery tray slides in and out. The inside of the tray and battery compartment look great. Stands about 13 tall to the top of the hat. Be sure to view all photos and feel free to ask any questions.
