The world of Coding Critters just got bigger! Meet Romper & Flaps, two new dino pals for Rumble & Bumble and stars of their own! This pair of playful toy dinos introduce kids to essential coding and STEM concepts through the challenges found inside their full-color 20-page adventure book. As kids help Romper & Flaps on their everyday STEM adventures, they’ll learn about fundamental kids’ coding skills, including sequencing, debugging, logic, trial and error, and more. Every screen-free challenge helps kids master early coding and preschool learning skills without the need for a phone or tablet. Feed them treats from their included food bowl, dream up new coding adventures that boost critical thinking and other STEM skills, or use the magnets in their noses to help them interact with other Coding Critters!
