They can be Sweet, Playful, Clingy, Energetic and Teasing. Sometimes when they touch a Human, some of their Goo goes on the Human, if the Human is covered in the Goo, the Human turns into a Sweety too! They are always happy, but can get a bit upset when harm is done to them. You can normally find them near the Art Room, which is where their Pinkish Red Puddle is, where humans can get turned into Sweeties.
