The Candy Kingdom Preschool is where the Candy Children are looked after by the limbless Candy Nanny, and possibly where they study. Unfortunately, the Candy Nanny is unable to discipline the Candy Children because of her old age and lack of limbs. The children even attack Jake, causing him to get very mad at them.
On the outside, it looks like a building with cream colored bricks and a red roof. It has a playground, and Finn and Jake made an obstacle course for the preschoolers. On the inside, there is one room shown with lots of toys such as a Princess Bubblegum plush. There are also many craft supplies in that room.
