The koala named Koko was a very clumsy creature. One day, Koko was trying to climb a tree, but he kept getting mixed up. He thought the 'd' was a 'b' and the 'a' sounded like an 'i'. Koko got so confused that he fell right out of the tree! Luckily, he landed in a soft bush. From then on, Koko had to be extra careful with his prefixes and suffixes when climbing trees.
