Unicorn Droppings

 The unicorn is a magical creature. Only the blood of the unicorn helped Voldemort stay alive. Unicorn droppings are purported to be the SOUREST things on earth. This is not a licensed Harry Potter item. These were created by the man who invented "Jelly Bellies" and they're the best soft-chew sour candy we've ever had. For witches and wizards only--not recommended for muggles
