A child feeds a little toy moppet corn and hay, kept snug in a pocket, only for a passing beggar to swear it away. Short and strange in the way old rhymes often are, with a plaintive last line worth a small sigh.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
I had a little moppet,
I put it in my pocket,
And fed it with corn and hay.
There came a proud beggar.
And swore he should have her;
And stole my little moppet away.
