Angryverse/The 4th Egg

The 4th Egg is a short comic posted by Rovio in 2015, revealing Silver's origins.

Plot
Her egg was found in a hidden area in the forest, where a minion pig found her and took it to King Pig. The king kisses the pig in joy. Obviously pleased, he commands the minion to send it to Chef Pig, where it could be cooked and eaten. Before Chef Pig begins cooking, the egg begins to slowly hatch, revealing a baby bird. A crowd of minion pigs gaze in awe at the newly born hatchling, much to the displeasure of the cook. One views the hatchling as their own bird and names her "Silver".
