Why Monkeys Swing in the Trees

You see there was a time when Monkey used to play on the ground and he loved to wind up Crocodile. One day the big rains came and Monkey became stranded up a mango tree. Nasty Crocodile promised to take him to dry land but only in exchange for his heart! So Monkey tricked Crocodile, and when Crocodile found out that Monkey swapped his heart for a measly mango, he chased Monkey up a tree. From that day on Monkey swings in the trees keeping well clear of Crocodile's angry snaps.
