"Got this here from a wizard on a bargin. Just the thing to survive the salvaging of treasure from the deep when you don't have a lot of start up cash. Not everyone can tame sea turtles mate, you know what I'm saying? This here is an item with it's own character, a real unique item, so beware of imitators! The surest way to spot a fake is have a friend try it, if he dies, all you have is a ordinary bucket and a funeral to pay for, this here is the one real deal you've been looking for and it's still available for a steal!"
