Prawns

Two prawns, Tom and Christian, were swimming around shark-infested waters discussing how difficult their lives were. “We never know when we’re going to get eaten,” said Tom. “I wish I was a shark, then I wouldn’t have to worry.”
At that moment, a shoal of cod appeared. “Your wish is granted,” they chanted and POW, Tom turned into a great white. Christian, terrified that his former friend was going to eat him, ran away and hid.
Months passed and life grew very lonely for Tom. Whenever he saw his old Prawn mates, they swam away in fear. Christian was so upset by his oldest pal joining the enemy that he refused to leave the house.
Desperate to put things right, Tom searched everywhere for the mysterious cod. Eventually, he found them. “please, make me a prawn again,” he begged. PUFF – he was a shellfish once more. With tears of joy in his tiny little eyes, Tom swam home to Christian. He banged on the door and said, “It’s me. Tom. Come and see how I have changed”
“No way,” Christain replied, “I’m not going to be tricked into being your dinner.” “But that was the old me,” implored Tom. “I’ve found Cod. I’m a prawn again, Christian.”
