Bringing the adventure of camping indoors, build your own fort or den. This entertaining set comes with 85 glow in the dark balls and poles that join together to build a fun play space. Build different shaped play structures from a fort one day and a tunnel, tower or hut the next - then cover with bed sheets and snuggle in to your cool new den. With an LED flashlight to charge and recharge the glow in the dark structure, perfect for sleepovers, indoor camping and rainy days. And way more fun than sheets on chairs!
