One day Turtle saw himself in the pond. What he saw made him unhappy. He thought his green shell looked so simple. Just then Bluebird flew past. Turtle thought Bluebird was lucky to have bright blue feathers and wished that he had beautiful blue feathers, too. Then Turtle noticed two of Bluebird’s feathers on the ground. He quickly picked them up and connected them to his shell with some mud from the pond.
Turtle walked up the path next to the pond feeling quite handsome in his new feathers. Soon he met Squirrel(松鼠), who began to laugh. “You look so silly!” Squirrel said. Turtle felt terrible. He thought Squirrel was lucky to have beautiful gray fur and wished that he had gray fur, too. Then Turtle noticed that Squirrel had shed some fur under a bush. So Turtle picked it up and connected it to his shell with some more mud from the pond.
Turtle walked up the path feeling quite attractive in his new fur and feathers. He couldn’t wait to show off his new decorations to his friend Frog.
He was happy when he saw Frog coming out of the pond.
“Hello, Frog,” Turtle called.
“Who are you?” Frog asked jokingly.
“I’m your friend Turtle,” Turtle replied.
“That can’t be,” Frog said. “My friend Turtle is a very handsome fellow with a lovely green shell. You are a foolish-looking creature.” With that, Frog hopped back into the pond. Turtle looked at himself in the pond once more. Frog was right, of course. He did look foolish. Turtle pulled off the feathers, the fur and the quills. His green shell was lovely after all.
