Surprise in Animal Land /p4
"An egg! We've never seen an egg like this!" "It is the egg of a magic bird," said Mr. Porcupine, wisely.
"Ah, ha!" laughed Mrs. Crow. "How silly you are! It isn't an egg. It's a balloon!" "Let's roll it back and forth," said Mrs. Rabbit. "But we can't let Mr. Porcupine play with it. His quills would burst it."
Mr. Porcupine was angry because they didn't let him play with the balloon. He hurried away and went to the home of Mr. Fox.
