This is not the "most" popular Lost In Space Toy Robot, more like a version that slipped through the cracks.  He is one of my most primitive robots, therefore one of my favorites!  He has basic appeal that can only be understood by holding him.  He does have a light in his halo, along with one behind the grid in his chest.  He sort of does a twist shuffle walk, pauses, then does it again repeatedly.  That's it, and that's why he is great!
