The Piggy Bank Event is a special sale that may appear for a limited time.

As you collect Golden Acorns, a matched amount goes towards unlocking the Piggy Bank. When the Bank is unlocked, a limited-time sale will be available for purchase. After unlocking the Bank, it will continue to grow as you collect additional Acorns, up to a maximum amount. The Bank will be available for purchase until the end of the event. Only one Bank can be purchased per event.

The Acorns that go toward unlocking the Piggy Bank are not diverted from your Season or Lifetime Acorns. They are a matched amount.
