Hard work only goes so far. Sometimes you need a miracle.
A Minion Pig tries to hammer down a nail. He gets mad and throws his hammer. The hammer falls on six pieces of wood with a pig at the end. The pieces of wood roll with a domino fashion and the last piece fall onto the pig. The pig rolls to a button which flew a Minion Pig to a tall stack of boxes with a wrench on top. The wrench falls on to a plank with an anvil on the left. The anvil falls and falls on another plank with an another pig. The pig flew off the plank and hit a pig in some sort of helicopter which made it crash on the nail and made it nailed down and the helicopter bounced off because of the spring. The Minion Pig hears the sound and looks back. Then, he sees that the nail is nailed down. He gets his hammer and walks away but he finds another nail that needs to be nailed down. He was about to hit the nail but instead, he threw his hammer and waiting for another miracle to happen. He waited but nothing happened yet so he moves forward a bit then checks the nail again. While he was staring at the nail, a Grand Piano falls down near the nail.
The falling piano may be a reference to the joke, "Show me a piano falling down a mineshaft and I'll show you A flat minor."
The thing shown after the pig threw the hammer is called a Rube Goldberg machine.
