The Money Tree is a type of tree featured in the Animal Crossing series. To grow them, the player must bury a bag of bells using a golden shovel. After the tree has fully grown, it may bloom with three bags of bells at amounts dependent on how much was initially buried. The tree will only bloom, and thus produce money, one time.
In Animal Crossing for the GameCube, money trees can be planted with the regular or golden shovel by burying money in the daily Shining Spot in the player's town.
Planting Money Trees can result in a great short term profit, but as a long term strategy, you will plant more than you pluck.
