Very rarely, a nest that reaches a certain level of maturity in which a queen is born will have an unusually large amount of biters in its population. Through a certain mutation process a queen will be crossed with a biter, thus giving birth to the most deadly, biggest, baddest gloople known to the universe: the biter queen, or razor queen. She also uses an advanced form of the "larva" technique to turn glooples and oozles into subordinate organisms with these blade-like spines.
