In the Haus DLC of Dead Island 2, you’ll need to find the A Gift for My Piggy Key to unlock the Piggy’s Bank lockbox. To find A Gift for My Piggy Key, finish the Haus DLC. Afterwards, make your way to the diner just past the forest.
Once there, take out Mrs. Piglet who will drop the A Gift for My Piggy Key.
Now that you have the A Gift for My Piggy Key, head into the diner and use the key to open Piggy’s Bank.
As a reward, you’ll receive the Sizzler blueprints!
