The cow PiepEi plays three different melodies for three degrees of hardness: OLD MACDONALD - for wimps MY GRANDMA RIDES A MOTORCYCLE IN THE HENHOUSE - for medium-soft eggs THE ROOSTER IS DEAD - for hard eggs On Sunday mornings, people don't plow on the farm, but breakfast is served. The perfect egg should not be missing. Too soft, too hard — but never to the point. Perfectly cooked eggs are a science in themselves. But no problem for the cow Piepei. Simply store with the eggs, cook them together with the eggs and wait until the cow sings Beep Egg. No matter what water temperature you start with and no matter what height you cook at, the egg will be perfect.
