the north pole

"It's--I wondered--It's only--Rabbit, I suppose you don't know, What does the North Pole look like?"
"Well," said Rabbit, stroking his whiskers. "Now you're asking me."
"I did know once, only I've sort of forgotten," said Christopher Robin carelessly.
"It's a funny thing," said Rabbit, "but I've sort of forgotten too, although I did know once." "I suppose it's just a pole stuck in the ground?"
