Vintage Electronic Gorilla Chimp Orangutan Stuffed Animal Plush Not Working READ

Vintage electronic monkey / gorilla / chimpanzee / orangutan stuffed animal plush. Appears to have a motorized mouth and arms (unsure if it is supposed to make sounds, or just movements) - NOT WORKING, sold AS IS as shown and described. Has a battery pack, but did not work when new batteries were added and tested - batteries will NOT be shipped or included. Could be a faulty wire, but we are unsure as we have not wanted to cause any further damage through troubleshooting. Does not have a tag or other branding that we could find. Please see photos for more details, and feel free to message us with any questions.
