Iwaya animatronic toy animals AS IS

This set of three plush animatronic toys are just adorable to look at. The cow does work but not very well. His battery casing does close properly, he’s got a little bit of dirt on his feet. The ram has a broken battery case and I cannot get him to work. The elephant I can’t get to work at all but his case does close. The cow and the ram were made in Japan. The elephant made in China. I’m hoping to find a home with someone who knows how to fix them!
