Kids sponges will be the biggest sellers... its one thing to take care of your car.... but I have yet to meet a kid that doesn't get every desired toy they want, on top of that, parents will love they can give their kid a sponge and he will enjoy cleaning himself.... it will be their biggest product seller in my opinion...
True I count the size of puddle pals sales will include those stores. That is why 100's of millions. Kids see on TV, Mom goes to Walmart with kid. Kid says mom I want that. Mom buys as it makes giving her kids a bath easier.
