Pooh sat down on a large stone, and tried to think this out. It sounded to him like a riddle, and he was never much good at riddles, being a Bear of Very Little Brain. So he sang Cottleston Pie instead:

Cottleston, Cottleston, Cottleston Pie,

A fly can't bird, but a bird can fly.

Ask me a riddle and I reply:

"Cottleston, Cottleston, Cottleston Pie."

That was the first verse. When he had finished it, Eeyore didn't actually say that he didn't like it, so Pooh very kindly sang the second verse to him:

Cottleston, Cottleston, Cottleston Pie,

A fish can't whistle and neither can I.

Ask me a riddle and I reply:

"Cottleston, Cottleston, Cottleston Pie."
