Alchemist Cookie

Made from the freshest of grapes, the fruit of the gods, this smart Cookie cares only about one thing: Research! She is always doing wild calculations, trying to figure out how to transform the elements. And she knows that being lazy or sitting idly by will achieve nothing. In order to acquire something of value, one must give something of value in return—that's Alchemist Cookie's theory, at least.
