“Owl, you and I have brains. The others have fluff”
“Owl,' said Rabbit shortly, 'you and I have brains. The others have fluff. If there is easy thinking to be done in this Forest - and when I say thinking I mean thinking - you and I must do it.”
“Use that fluff of yours you call a brain.”
“You could have heard a bee fluff”
“I want my fluff-fluff! (Bob)Fluff-fluff… (Zarek looked panicked.) (Zarek)”
“No brain at all, some of them [people], only grey fluff that's blown into their heads by mistake, and they don't Think.”
