I remember watching this show roughly 18-20 years ago. It was about a guy and a vollyball-sized, hovering eyeball. I can't remember, but i think the duo worked as detectives of some sort. I was 7-9 when I watched this show, so I can't recall many details. Also, its possible my brain made up this small detail, but I think the intro to the show would have like schematics and drawings of the giant eye.
Does this ring a bell to anyone?
