This one is really fun and seems to be rather rare as I cannot cross match it using image searches. I thought it might be Gemmy but I could not find any branding on it indicating that. This is super loud! It says something like ooh you scared me as it tries to hop.. see those powerful feet? So basically it moves around on the floor. I wouldn't call it a full hop but it's trying to. If it did a full hop, it would fall over. So it's designed to do what it does. It has batteries in it now and I will leave those in but depending on when it sells they may no longer be working by the time you receive it. Right now it sounds super loud so I'm guessing they're pretty fresh as of the time of this listing. I didn't want to use a screwdriver to take it apart. The eyes flash red while it is busy screaming/moving. There is an on-off switch on the back under the outfit. A great find for the collector of rare vintage halloweeniana! From a smoke-free home.
