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.""
