Taffy Girl is a Candy Person who appears in "Slumber Party Panic." Finn uses her taffy as blindfolds for the Candy People, so they will fearlessly hit the "piñatas," which were actually Candy Zombies. Since Candy People are gullible, they put on the makeshift blindfolds and readily believe that the zombies are piñatas, attacking them with sticks and bats. When Finn plucks off two of her taffy strips, it does not seem to hurt her. Taffy Girl also makes a cameo in "Susan Strong."
Taffy Girl's is similar in shape to an alpaca. However, she has white strips of taffy covering her body instead of fur. She has eyes that are similar to Jake's and Lady Rainicorn's, although Taffy Girl's are not quite as big.
