What was That Childrens Toy Tunnel That was sold years ago, a long collapsible tunnel you crawled through?

I used to have a toy when I was little, it was a collapsible Tunnel that kids could crawl in and out of, it was about 10 feet long when stretched out, then it collapses to the size of a hula hoop when your done with it. What is this toy called?|||Perhaps "Cray Curly Tunnel," which l fits your description, is the one? You may view an image at the site below.
