Wow, I never knew such strange animals existed. Apparently some twisted scientists out there are cross breeding all kinds of various species. My favorite, for the sake of its name, is the zeedonk--also known as the zebrass, zebronkey, zonkey, zebadonk, zenkey, zebrinny, or deebra (thanks to Wikipedia).
