Our hero is a piglet named Pig Mock. He has to catch all the eggs that mean Thunder Pants hurl at him and throw back only the red eggs. But if Pig Mock is too absorbed in hurling back the eggs, here comes Uncle Dust Pan to clean up the mess. You must jump to avoid being swept up together with the broken egg shells. It's a thrilling, exciting game for you!
