They had come to a stream which was twisted amd tumbled between high rocky banks, and Christopher Robin saw at once how dangerous it was.
"It's just the place," he explained, "for and Ambush."
"What sort of bush?" whispered Pooh to Piglet. "A gorse-bush?"
"My dear Pooh," said Owl in his superior way, "don't you know what and Ambush is?"
"Owl," said Piglet, looking round at him severely, "Pooh's whisper was a perfectly private whisper, and there was no need----"
"An Ambush, as I was about to explain to Pooh," said Piglet, "is sort of a Surprise."
"If people jump out at you suddenly, that's an Ambush," said Owl.
"It's an Ambush, Pooh, when people jump at you suddenly," explained Piglet.
Pooh, who now knew what an Ambush was, said that a gorse-bush had sprung at him suddenly one day when he fell off a tree, and he had taken six days to get all the prickles out of himself.
"We are not talking about gorse-bushes," said Owl a little crossly.
"I am," said Pooh.
"Hallo, Pooh," Owl said. "How's things?"
"Terrible and Sad," said Pooh, "because Eeyore, who is a friend of mine, has lost his tail. And he's Moping about it. So could you very kindly tell me how to find it for him?"
"Well," said Owl, "the customary procedure in such cases is as follows."
"What does Crustimoney Proseedcake mean?" said Pooh. "For I am a Bear of Very Little Brain, and long words Bother me."
"It means the Thing to Do."
