The Universally Challenged

Coobies live in abundance inside the master vault of the bank on Tibula. They can digest any form of currency and excrete a different currency at reasonable exchange rates. They can also do the same with precious metals and gems. Sometimes the owners of large diamonds return to the vault to find their precious gems converted to the Albanian lek which can be a little unsettling. In the wild they can accidentally get into wallets and purses causing mayhem on a night out. Most English pubs do not accept cowrie shells as currency whereas you might get away with it in the country of Benin.
