"Pooh!" squeaked the voice.
"It's Piglet!" cried Pooh eagerly. "Where are you?"
"Underneath," said Piglet in an underneath sort of way.
"Underneath what?"
"You," squeaked Piglet. "Get up!"

Pooh said, "Let's go and see Kanga and Roo and Tigger," and Piglet said, "Y-yes. L-let's" - because he was still a little anxious about Tigger, who was a very Bouncy Animal, with a way of saying How-do-you-do which always left your ears full of sand, even after Kanga had said, "Gently, Tigger dear," and had helped you up again.

"Supposing a tree fell down, Pooh, when we were underneath it?"
"Supposing it didn't," said Pooh after careful thought.
Piglet was comforted by this.

So Owl wrote...and this is what he wrote:
HIPY PAPY BTHETHDTH THUTHDA BTHUTHDY
Pooh looked on admiringly.
"I'm just saying 'A Happy Birthday'," said Owl carelessly.
"It's a nice long one," said Pooh, very much impressed by it.

"So it does!" said Pooh. "It goes in!"
"So it does!" said Piglet. "And it comes out!"
"Doesn't it?" said Eeyore. "It goes in and out like anything."

"Eeyore, what are you doing there?" said Rabbit.
"I'll give you three guesses, Rabbit. Digging holes in the ground? Wrong. Leaping from branch to branch of a young oak tree? Wrong. Waiting for somebody to help me out of the river? Right. Give Rabbit time, and he'll always get the answer."
"But, Eeyore," said Pooh in distress, "what can we - I mean, how shall we - do you think if we -"
"Yes," said Eeyore. "One of those would be just the thing. Thank you, Pooh."
