Pongpong Flower is a large children's indoor playground on the first basement floor of Star City in Jayang 3-dong, Gwangjin-gu, Seoul. It has wide play areas and many rides for children, and a restaurant inside serves simple food. Seating is set aside for guardians, and families stay for several hours at a time. The entrance is at the D95 pillar in the second basement parking lot, which makes it awkward to find on a first visit.
