There's a heck of a draught coming through the door, and I suddenly realised why it's so cold - the wind is from the north. That immediately lead me to remember 'The north wind doth blow, And we shall have snow, And what will the robin do then, poor thing?' but I then had to google because I couldn't remember the fourth line.
I was flabbergasted to discover that there were four other verses as well.

The north wind doth blow,
And we shall have snow,
And what will the robin do then, poor thing?
He'll sit in a barn,
And keep himself warm,
And hide his head under his wing, poor thing!

The north wind doth blow,
And we shall have snow,
And what will the swallow do then, poor thing?
Oh, do you not know
That he's off long ago
To a country where he'll find spring, poor thing!

The north wind doth blow,
And we shall have snow,
And what will the dormouse do then, poor thing?
Roll'd up like a ball,
In his nest snug and small,
He'll sleep till warm weather comes in, poor thing!

The north wind doth blow,
And we shall have snow,
And what will the honey-bee do then, poor thing?In his hive he will stay
Till the cold is away,
And then he'll come out in the spring, poor thing!

The north wind doth blow,
And we shall have snow,
And what will the children do then, poor things?
When lessons are done,
They must skip, jump and run,
Until they have made themselves warm, poor things!

Sadly a google search for
"I've expect you've all heard of Mister Mole,
Who lives in the groind in a big deep hole.
Mister Mole likes worms for tea -
Juicy and fat, and big as can be."
which I first read in 'Sunny Stories' a magazine edited/mainly written by Enid Blyton resulted in no hits though I think there was at least one more verse.

One verse that I did learn from that magazine was

"When cats run home and light is come,
And dew is cold upon the ground,
And the far-off stream is dumb,
And the whirring sail goes round,
And the whirring sail goes round;
Alone and warming his five wits,
The white owl in the belfry sits"

Because it was in the magazine I always thought that Enid Blyton wrote it, but I now find that it was written by a fellow Yellow-Belly, Alfred Tennyson. I have a vague recollection of the second verse, but mainly remember the last two lines of each verse.

"When merry milkmaids click the latch,
And rarely smells the new-mown hay,
And the cock hath sung beneath the thatch
Twice or thrice his roundelay,
Twice or thrice his roundelay;
Alone and warming his five wits,
The white owl in the belfry sits."
