I have thought that this toy is one of the funniest things that I have ever seen, and now it is being called the most popular Christmas toy of 2011. If you have not seen this shark blimp you must be living under a rock because it has been on television, and in ads all season long. It is a remote controlled helium filled shark that you can make swim through the air in your home. I kind of would like to have one myself, but I heard that helium tanks cost quite a bit to refill and that is not cool to me. I guess it comes with one full tank though, but Im assuming due to the size of the thing it doesn’t last long!
