Kids can solve puzzles, explore physics, learn coding basics, practice math, mix colors, create music, and join missions to save the day. Developed by StoryToys in partnership with Sesame Workshop, this app provides a trusted, kid-safe learning experience. Free to play with optional paid content, it ensures endless fun and learning. Download now and let your child explore a world where knowledge meets creativity!
Launch the app and meet Mecha Elmo, Cookie Monster, and Abby Cadabby. Choose a character to start your STEM adventure. Navigate through the main menu to select activities like puzzles, coding games, or coloring. Each activity introduces a new challenge, such as helping Cookie Monster use his slingshot to hit a target or mixing colors in the Crayon Factory. Follow on-screen prompts to explore at your own pace.
Engage in missions where the Mecha Builders use their robo-skills to solve problems. For example, in Cookie’s Bouncy Quest, kids learn about force and trajectory by helping Cookie reach a target. Other activities include building devices with Mecha Elmo or using Mecha Abby’s jet boosters to navigate obstacles. Each challenge encourages critical thinking and creativity.
Help Mecha Cookie Monster use his slingshot to hit a target in a forest setting. Kids learn physics concepts like force and motion while overcoming interactive obstacles. Success unlocks rewards, keeping young learners engaged.
Mix colors to create crayons and color back-to-school templates. This activity fosters creativity and teaches color theory as kids pack a backpack and hop on a bus to meet new friends. Perfect for preparing for school in a fun way!
The app is designed for children aged 2 to 6, offering age-appropriate STEM activities and games.
Yes, the app is free to play, but additional paid content is available via a subscription service that unlocks all content, including future packs.
