Our 16 month old son uses Pow-Pow for fish because of this book. He can't make an F sound quite yet so he associated that word with fish.
He also says "aga" for alligator. He was saying it non-stop last weekend when we did a staycation at a hotel and some kids had an inflatable alligator in the pool.
Ooo a pout pout fish Challenger!
Enjoy!
Are you a Pout Pout Fish?
