Donald's Magic Stone

Donald's Magic Stone is a book in the Mickey's Young Reader Library series.

Summary
Donald Duck spends all day chopping wood but forgets to buy food. When he spots Goofy walking with an armload of groceries, he hopes to be invited for supper. He picks up a sparkly rock and tells Goofy it's a magic stone that can make soup from boiling water. Goofy invites him in and they put the rock in a pot. Donald says the soup would be better if they added carrots, then onions, then more and more ingredients. Then he says the soup would be great if served with bread and butter and sausages. After they've eaten, Donald admits the stone wasn't magic, but Goofy says it really is, look how it made his groceries disappear!
