Kohlrabi is a vegetable that tries to disguise itself as a root vegetable, but thanks to something wierd it sticks out of the ground with one long, giant root. Many Normies don't know this, this is why they only eat meat. You can use it's leaves to make Kohlrabi Chips that you can use to channel your inner Troll.
Kohlrabi was invented in Germany when Heinz Doofenshmirtz created, "The Root Veggie-inator" for a science fair, but he lost to a baking soda volcano. Enraged, Heinz Doofenshmirtz shot the kid with this invention, but since Cauliflower flavored Gum was stuck in his, "-inator" it turned him into a root vegetable that actually wasn't one, he named it, "Kohlrabi" in memory of Balloony as it sounds like Balloony.
