Cat looked all over. Cow looked all over. They did not see anything blue. They did not see anything new. Then Cat saw something. "There it is!" she said. "It is blue and it is new! It is a wagon!" "I am too big to ride," said Cow. "But I can pull!" Cow pulled and pulled. Then Pig pulled and pulled. The three friends went round and round. "Look!" said Cat. "Over there! I see something blue again!" "I see something yellow," said Pig. "I see something red and green," said Cow. The three friends went out of the barn. They looked up. The sky was blue. And there was a rainbow!
