A big lion was just dropping off to sleep one dark night when he heard a strange croaking noise that seemed to come from the lake nearby. The lion put his paws over his ears, but the darker the night the louder the noise. The lion began to have nightmares. "There's a dreadful monster living in the lake," he thought. "It comes out at night to eat lions." He lay flat under a bush, hardly daring to breathe. At last, the first grey light appeared. The lion looked out fearfully, but all he could see were dozens of bullfrogs croaking away. Fancy being afraid of the dark," he said to himself. "What a big silly I am."
