The chest light does still work but it is finicky as the control buttons need to be worked on. I installed batteries not included!! and was able to get the light to come on by pressing the walk and bend buttons. I will leave that to you. I recently bought a house and its contents and found several toys in remarkably great condition.
This item has very few nicks or scratches and is in great shape. His ears are intact and the packaging is in incredibly good shape for a 57 year old item. The original inserts are included in the pictures and help to secure him into the box. The original instruction sheet is included as well.
The hand sponges are pictured but are very brittle. No guarantee on how they will arrive. I found no rust or corrosion on the robot. There is some residue from old batteries inside the battery casing but it is minor and not visible when closed.
