This could be related to a few issues. The Zoomer has gears that open and close the mouth. Those gears are hooked to some wiring running from the main circuit board. I would open up the device, inspect all the wiring, and inspect the gears for any flattening or rounding on the teeth. Stay tuned for one of our repair guides that will show you the step-by-step on how to open up the device for inspection and repair!
