It's a special day for one of the Minion Pigs, but do the other pigs know - or even care?
The episode begins with the sun rising over the Pig kingdom. A pig wakes up to sound of a wake up call that is similar to a rooster's crow. Afterwards, Corporal Pig unscrews a cork that is used as a door in one of the buildings and releases lots of Minion Pigs out into the open. Some of them are still sleepy, but others are brushing their teeth. One of the pigs excitedly jumps around about because it is his birthday. He puts a birthday cap on and starts blowing a birthday whistle to get everyone excited. However, none of the pigs seem to care. Corporal Pig then walks over to the birthday pig to stop his annoyance, only for the birthday pig to blow the whistle into Corporal Pig's snout, enraging him. Later that day, the birthday pig is thinking about a huge birthday cake while sawing down a tree, which falls on him as a consequence of him not paying attention. Corporal Pig sees this and then orders the birthday pig to carry the King Pig on his throne back to his castle. After that, he walks into the palace with King Pig to see a great big cake, while Ludwig van Beethoven's Symphony No. 9 plays. For a while, he thinks that the cake is meant for his birthday until King Pig literally dives into it and eats every scrap, even the candles. A smaller piece fell next to birthday pig, exciting him, but then the King Pig eats it before he can, much to his disappointment. When night falls, the birthday pig walks into the building in a saddening state with other pigs. The episode ends when the other pigs unexpectedly light a candle on a smaller birthday cake just for him during the night, while Symphony No. 9 plays and revealing the surprise party.
