Step 2

              Opening the Body

Once the battery compartment is removed, remove the screws on the side of the body.
It is best to use a sorting tray or other method to keep track of each screw and determine where it goes.
Remove the blue plastic tabs at the base of the tail and at the mouth joint on the same side of the body.
Remove the screws hidden underneath these tabs, and pull lightly on the body to open it.
The halves of the body are still attached via wires, so be careful not to break them.
The LED Mood Indicator cover, tail markings, and tail will detach when the body is opened. Additionally, the tail can be detached without disassembly by pulling firmly on it.

              Opening the Leg

After the leg has been removed from the body, remove the screws securing the wheel covers.
With the wheel exposed, hold it down firmly, so it does not rotate, and remove the screw in the center. This can be difficult to remove.
Though the wheel can be removed without unscrewing it first, it will detach a gear from the gearbox, so please remove the screw first.

Step 6

              The Fix

A Ferris wheel-shaped part should be connected to the gearbox motor’s axle. Ensure it is not loosely connected or missing. If loose, push it further down the axle and into place.
If necessary, you can open the gearbox by removing the screws surrounding it.

Step 7

              Reassembly (1)

Route the wiring through the hole in the rear casing, and reattach all screws.
Reattach the wheel to the leg and secure it with the screw.
Reconnect the wheel covers and attach the screws.
Route the wires through the opening in the body, and reattach it to the connector.
