There's something fishy going on here.
Whoosh.............James becomes a shark and swims off.
Two weeks later James is upset. All of his old friends are now afraid of him and his life is miserable. He decides to use his second wish, and he wishes to be a prawn once again.
Whoosh....Now a prawn again, James swims away to look for his mate Christian.
When he arrives at Christian's house he knocks on the door and shouts out for Christian.
"Go away", says Christian, "you're a shark and you'll just eat me".
"No I won't", shouts James, "I'm a prawn again Christian".
