X is the name given to a large-mouthed frog species from South America known for its ferocious appetite. It attempts to eat anything moving close to it.

A Massachusetts bakery was warned by the FDA for listing the ingredient "X" in their granola, which was actually a nod to the passion bakers put into their product.
