Review on WALIKI Hopping Inflatable Ridding Included by Steven Barbon

Given to my son for Christmas this year. He JUST turned 3 years old on December 5th. After reading the product description I thought it sounded perfect for him bouncing on his sister's purple ball. Such a disappointment. The idea is cute and maybe we were just unlucky and got the wrong design. The picture in the description is far from what we received. Once inflated, even if fully inflated, it will NEVER fill the dinosaur cover. So it's loose and shifts every time my son sits on it. It's also ridiculously TOO small for him, so the fact that it's supposed to be perfect for kids ages 3-5 is imprecise and unrealistic. It absolutely 100% does NOT bounce. He enjoys sitting and hopping up and down a bit, but to actually hop he literally has to hold on to the handles and pull with each hop. This was a huge disappointment that I can't even return because it was supposed to be from Santa Claus.
