My son stretched this popular Sonic The Hedgehog toy out and got it around his neck somehow and couldn’t get it off. It has a gummy/tacky texture to it and was twisted on itself and was not budging when he was trying to pull it off, it was extremely tight. The toy tries to return to its original shape so it has a natural shrinking tendency to it.
My son had a red face and fear in his eyes when I was getting it off his airway. It scared us both. I’d definitely recommend supervised play if any at all. The toy is rated 3+, but my 4 year old wasn’t strong enough to remove it from his neck.
