Fintastic storytelling
Format: Hardcover
Awesome book for shark fanatic kids. I bought this book for my 7yr son and it was so informational that I even learned something . And if you would just like to read the book you can and in between you want switch and l3t the story teller read. They are both fun for a lil boy to read with someone or the storyteller.
