Piggy Bank 
Effects
- Adds 3 coins on pickup.
- When Isaac takes damage, there is an equal chance for 1 or 2 Pennies to drop.
Notes
- If (Keeper) Keeper or (Tainted Keeper) Tainted Keeper collects this item with 1 health coin, it will heal a coin and add 2 coins to his inventory.
- (Added in Repentance) If (Keeper) Keeper has unlocked a third health coin, collecting this item may heal 2 health coins and only provide a single coin to his inventory, depending on whether he has 1 health coin remaining or 2.
- Unlike the coins dropped from being hit by a shot from a Keeper, Greed, or Super Greed, the coins that are dropped from the piggy bank are not subtracted from Isaac's total.
- Can appear in the shop and the item room on the same floor, but picking up multiple copies of the item does not cause its effect to stack.
- The drops from Piggy Bank, unlike (Swallowed Penny) Swallowed Penny, are locked to normal pennies, instead of random types of coins.
