Robot Strength & 3-in-1 Building Fun
Bring bold Robotryx adventures to life with Grindburst, a strong and rugged robot toy made for hands-on building, action play, and creative construction. With 235 building bricks and a distinct red-and-black design, Grindburst gives kids an exciting way to explore robot play while building a complex form.
-
Customize with DIY Glow-in-the-Dark Stickers
Kids can personalize their build with a themed sheet of glow-in-the-dark stickers made to match the robot’s style. The DIY fun comes from choosing where to place each glowing detail — stars, badges, symbols, panels, and action accents — to transform the figure into a glow-in-the-dark creation. Once the lights go out, the stickers shine and bring extra excitement to every adventure.
-
Shape-Based Building & Creative Play
Grindburst can be rebuilt into three fun forms: a powerful robot, a cool vehicle, and a fierce animal. Kids can discover how different shapes and building elements fit together, experiment with new combinations, and create exciting adventures that encourage imagination, coordination, and problem-solving through play.
