Money Trough

The Money Trough is a summoning item that summons the Flying Piggy Bank, a temporary floating winged version of the Piggy Bank. It has a /  chance to drop from the Drippler and the Blood Zombie during a Blood Moon, or with a much lower ( / ) chance from their statue-spawned versions (regardless of whether a Blood Moon is occurring). It also has a chance of dropping from the  and, which can be fished up during a Blood Moon.

The Money Trough enables players to access their Piggy Bank contents without having to place the Piggy Bank or any furniture for it to rest on. The Flying Piggy Bank despawns after 3 minutes, but can be re-summoned repeatedly at no cost. The Flying Piggy Bank does not follow the player like pets or minions would, instead it hovers stationary at the point summoned. Once summoned, other players may use it as well to access their own Piggy Bank.

Tips

 * It can be used to store situational, less-used items, e.g. hammers, potions, fishing equipment, or alternate armor or weapons, which would otherwise clog up inventory space.
 * It is a useful item for Expert Mode players, who lose 75% of their coins upon death, and players, who lose 100% of their coins, rather than 50%, due to its ability to allow a player to deposit their coins at will, regardless of their location.
 * The Money Trough is a useful item through the whole game, and can be obtained early. With some preparation, it can be obtained after a single Blood Moon.
 * It may be worthwhile to hold off on defeating the Wall of Flesh until after acquiring a Money Trough, as Hardmode Blood Moons have a much higher variety of enemies, making it an even rarer drop.
 * When buying from a vendor NPC, the coins stored in the Piggy Bank via the Money Trough will be used if there is not enough in the inventory.
 * To get the Money Trough more quickly, the player may place a Water Candle or consume a Battle Potion, as the Blood Moon does not have a set spawn rate.

Trivia

 * The Flying Piggy Bank is an allusion to the phrase when pigs fly, a figure of speech used to humorously describe something that is thought to be impossible or will never happen.
 * When spawning or despawning the Flying Piggy Bank, it emits an oink, sometimes with slightly differing pitches.
