Although it's difficult to find Gremlins with these legs/feet in the film, it is possible. I'm sure you're right that they were designed as a prototype, but they were absolutely used as stunt puppets in the film. When Gremlins are smashed up against walls, or strapped onto actors as they run around the hallways, it is often puppets with this style legs/feet. I suppose Neca got their hands on whatever they could, and it isn't surprising that what they could manage was a stunt puppet.Neca should describe that Gremlin as what it really is: a replica of a PROTOTYPE gremlin from Gremlins 2... indeed, these legs were never used in the film, but only on prototypes. All the screen-used gremlins have thinner and smoother legs with longer and thinner toes... These particular legs they used can be seen on pre-production, "making of" pictures, but never in the movie. Strange choice for a replica!
