Here is the full poem:
The Pixie Shop
In a dingle near the very top,
A little pixie keeps a shop.
With a wink and a smile and a wave of her hand,
She'll sell you a star from a far-off land;
Or a cloud for a pillow, or a rainbow bright,
Or a drop of dew to make you sleep sound at night.
She'll sell you a moonbeam, and a feather from a bird,
And a song of a lark that you've never heard.
She'll sell you a sigh from a daisy so white,
And a little green leaf to make you feel light.
So if you are tired and your spirit is low,
Just visit the shop in the dingle, you know.
