Fill the reusable scenes with more than 175 cling-style stickers, and create your own dinosaur-filled prehistoric adventures! To set the scene and spur the imagination, five glossy, full-color backgrounds (prehistoric ocean, Triassic, Jurassic, Cretaceous, and Ice Age) feature lots of space to play creatively. They pull out cleanly too--so this cool set is easy to share. The colorful, kid-friendly stickers (for ages three and older), are organized by time period, stick easily, pull up cleanly, and can be used again and again to keep bringing prehistoric stories to life.
