Old Mr. Toad in "Old Mr. Toad Gets His Stomach Full"

"Help yourself," said Buster Bear politely.
Old Mr. Toad didn't wait to be told twice. He forgot all about his fright. He forgot all about Buster Bear. He forgot that he wasn't hungry. He forgot his manners. He jumped right in among those ants, and for a little while he was the busiest Toad ever seen. Buster Bear was busy too. He swept his long tongue this way, and he swept it that way, and each time he drew it back into his mouth, it was covered with ants. At last Old Mr. Toad couldn't hold another ant. Then he remembered Buster Bear and looked up a little fearfully. Buster was smacking his lips, and there was a twinkle in each eye.
