Although little is known about it at the moment, it is said that taking a WooHooium ingot and putting it on either side of a double bed means that no WooHoo will ever be rejected. Little hearts appear from the ingots when the WooHoo is in progress. This metal looks different from other metals; WooHooium has a heart on it in the space (on the ingot itself) where most metals in The Sims 3 have a Plumbob.
