4998 Stegosaurus is a Creator set released in 2008, which contains 731 pieces to build a Stegosaurus with 4 long spikes on his tail, and eyes that light up using a Power Functions light-up brick. The eyes are made out of glow-in-the-dark plastic, so it continues to appear illuminated even when the light-up brick is not turned on. It also includes instructions for a T-Rex and a Pterodactyl, however, only 1 can be built at a time. This set is recommended for children aged 7 through to 12.
