This is a Hopper Ball. It is an inflatable rubber ball with a single handle at the top, which you can sit on, & bounce. It's sort of like an inflatable chair, but it's made of very springy rubber so it acts sort of like an extremely simple pogo stick...only you're sitting & never get to spring up very high. See what's going on, on the box picture? That's exactly all that it is good for. The Sonic graphic is nice, with rings, stars & Knuckles, Amy, Cream & Tails.
