Snap! has a similar theme. When mother Duck finds an abandoned egg, she rolls it home to her nest.

Her own eggs hatch out one by one into fluffy ducklings - but the foundling egg, Snap, turns into a baby crocodile.

Mother Duck insists there's nothing unusual about it, and when a greedy tiger tries to snatch all the ducklings, sure enough it's Snap who saves the day.

A delightful story, gorgeous pictures and a flavour of family warmth all combine to make this a really great book to share.
