Not a 'Swapper' but use of waddle in an old rhyme:

Old Mother Widdle Waddle jumpt out of bed,
And out of the casement she popt her head,
Crying, the house is on fire, the grey goose is dead,
And the fox he is come to town Oh!

From Gaffers and Gammers CLXXVI, Halliwell, The Nursery Rhymes of England, 1846, 4th ed.
