He sat up on his hind legs and listened, as all rabbits do.

“No, I can’t hear it now, either,” said Flop Ear. “But I heard it very plainly a while ago. Come on, let’s run. It may be danger!”

So Flop Ear and Pink Nose ran along together, until, in a little while, not far from their home, they saw Snuggle, who was poking about among the leaves.

“What are you looking for, Snuggle?” asked Flop Ear.

“For some sweet roots to eat,” answered the little sister rabbit. “But why are you two running?” she asked, in bunny language.

“Flop Ear heard a funny noise,” said Pink Nose. “He is going to tell papa and mamma about it, and I am going with him.”

“It may be a danger-noise, such as Grandma Munch tells about,” added Flop Ear.

“If it’s danger I’m not going to stay here,” Snuggle cried. “I’ll go with you.”

So the three little rabbits ran along together, and they soon reached the underground house. Lady Munch was sitting at the front door, looking all around. She had just finished making up the leaf-beds, and she wanted to come out in the air.
