Shula,
I'm not sure about the wisdom of mixing my doggerel with Milne's rhyme, but if you replace the last verse with this it at least fits the tune:-

And so in the end he did nothing at all,
But basked on the shingle wrapped up in a shawl.
When it rained he got wet but when it was fine
He sat all day long in the blazing sunshine.

And when he grew hot he would sit in the shade
And bask for a time in the coolness it made,
And I think it was dreadful the way he behaved ---
He did nothing but basking until he was saved!

PS As Milne played cricket for England he was a better cricketer than I am too!

Cheers,
Alan
