Missy is a character that appeared in Freshly-Picked Tingle's Rosy Rupeeland.
Missy is a very intelligent girl who appears early in the game. Tingle must bring her Ground Shell and Minced Meat. After Tingle succeeds in doing this, Missy will give him the recipe for Tingly, a medicine which he can then bring to the Guard to help his sick wife. The medicine can also be made to give to Tingle's Bodyguard.
Later in the game, Missy is lost in Lon Lon Meadow. Tingle has to find her glasses in order to save her. Missy's father, the Jeweller, will then reward Tingle for Missy's rescue. For the rest of the game, she will be in the most eastern part of Port Town. If Tingle speaks with her after he has reached the second continent, she will tell him about a medic in the Gooey Swamp who has invented a new medicine, Tinglene. Once he has reached the Third Continent, she will tell him about the Shaman of Mount Desma who has invented another new medicine, Mega-Tingly.
Madame Scratchcard, a character that appears later in the game is probably her mother because of the fact that she stands next to the Jeweller, Missy's father, and also lives in the same house.
