I'm a riddle in nine syllables,
An elephant, a ponderous house,
A melon strolling on two tendrils.
O red fruit, ivory, fine timbers!
This loaf's big with its yeasty rising.
Money's new-minted in this fat purse.
The speaker refers to her enlarged belly in an exaggerated way, suggesting that her legs are like tendrils on growing melon plants, also giving the impression her movement is precarious.
