Meet the Coding Critters: your first coding friends! These playful dino pets bring early STEM concepts to preschool learning through 100% screen-free coding. Kids code along with their new pets’ storybook adventure, and help the clumsy Rumble and bumbling Bumble have a playtime they'll never forget! Each storybook coding challenge unfolds in the Coding Critters' fun pet playset - can you code Rumble to play hide and seek, chase down a boulder from his volcano launcher, or knock over his break-apart cave? In addition to following along with the storybook's coding challenges, you can also use the pet playset to design your own code games and more! The Coding Critters also double as cute interactive pets - press Rumble's nose to activate Play Mode, where you can feed, pet, and take care of your new dino robot pal! You can even make him dance and sing a silly song! Requires 3 AAA Batteries.
