"Little Mr. Squirrel did. People who, like Peter, did not use their eyes, thought that he could fly, and he was called the Flying Squirrel. He was the great-great-ever-so-great-grandfather of Timmy whom you both know."
"And Timmy doesn't really fly at all, does he?" asked Jimmy Skunk.
"Certainly not. He jumps and slides on the air," replied Grandfather Frog.
"What did I tell you?" cried Jimmy triumphantly to Peter.
"Well, anyway, it's next thing to flying. I wish I could do it," replied Peter.
