Vintage Louie Frog Chantilly Lane 19" Not Working READ

Supposed to sing what a wonderful world and mouth should move. Someone left batteries in. I cleaned battwr box and tried new batteries, but still not working, but he is still cool sporting the bow tie and straw hat! THIS WAS UN A SMOKING HOME AND I AM WORKING TO REMEDIATE THAT. IF YOU CANNOT DEAL WITH A LIGHT SMOKE ODOR, DO NOT BUY THIS.
