The Whuddleville Bank is a place where whuddlebeans and items can be stored. It is run by Mr. Ban K. Ruptcy, who also hosts the weekly lottery at the BBB Boards.
There is an ATM machine that can be used to deposit and withdraw whuddlebeans, check their account balance or whuddlebean history. Citizens can apply for a card, which, along with a PIN, activates the ATM.
There is also a vualt for storing items. There are only 20 spaces by default, but it can be expanded using DazzleDabs.
