Pompion Potion is learnt in first year Potions at Hogwarts School of Witchcraft and Wizardry. Once drunk, the potion temporarily turns the drinker's head into a pumpkin. In order to brew this potion, one has to crush the Flitterby Moth into a pulp and add it to the cauldron, then stirr the mixture clockwise until it turns green. Next, the Bouncing Bulb has to be ground with a mortar and added to the cauldron. The mixture has to be stirred anti-clockwise until it turns red before slicing the foxglove and, too, add it to the mixture. Stirring clockwise until it turns orange completes the potion.
