One day, in the shark-infested waters of the
Caribbean, two prawns called Justin and Christian are discussing
the pressures of being a preyed upon prawn.
"I hate being a prawn," says Justin. "I wish I were a shark."
Suddenly, a mysterious cod appears. "Your wish is granted," he
says.
Instantly, Justin becomes a shark. Horrified, Christian swims away,
afraid his former friend might eat him. As time passes, Christian
continues to avoid Justin, leaving the shrimp-turned-maneater
lonely and frustrated. So when he bumps into the cod again, he begs
the mysterious fish to change him back. Lo and behold, Justin is
turned back into a prawn.
With tears of joy in his tiny little eyes, he swims back to the
reef to seek out Christian.
As he approaches, he shouts out: "It's me, Justin, your old friend.
I've changed & I've found Cod. I'm a prawn again,
Christian."
