Magical Prank. The unfortunate result of a magic school prank, alchemical skunks were created when an ordinary skunk was forced to drink a combination of potions. Despite their larger size, alchemical skunks still look and act like ordinary skunks, except for the ever-changing color of the stripes on their backs. Experienced foresters know that the colors on the alchemical skunk's back indicate which magical malady the creature is about to spray and do their best to avoid aggravating these dangerous creatures.
