Grindburst Extra Pieces
What Grownups are saying?
Why It's Awesome?
-
More Armour for the Tough Guy
Grindburst was never built to be delicate. This pack adds 235 pieces in his signature red, black and grey — enough to thicken the armour, widen the shoulders and turn a strong bot into a genuinely intimidating one. Kids can keep building outward until he looks like he could take a hit.
-
Grindburst's Own Specialty Pieces
Beyond the everyday bricks, this pack carries the shaped pieces unique to Grindburst — the angled plates, drill details and heavy connectors that make him look like himself. They are the parts you cannot substitute from another set.
-
One System, Endless Remixes
Every Robotryx set speaks the same brick language. Tip this pack into any other Guardian's box and something brand new rolls off the workbench — a taller robot, a wilder creature, a machine nobody has invented yet. The best builds usually start with "what if we combined them?"
Why parents love it?
Every JitteryGit toy is designed with parents in mind — safe, durable, and built to spark real learning through play.
-
Rescues a Half-Finished Build
One missing piece is all it takes to stall a build and sour an afternoon. This pack puts the spares back in the box so the robot gets finished.
-
The Smallest Way to Restart a Favorite Toy
A toy they have already built once can feel finished. A handful of new bricks makes it interesting again — no new toy required.
-
Builds Focus, Patience & Fine Motor Skills
Sorting, connecting and problem-solving with smaller bricks supports coordination, concentration and the satisfaction of sticking with something tricky.
-
An Easy Add-On Gift
Small, self-contained and genuinely wanted — a straightforward stocking filler, party favour or reward for the kid who already owns the robot.

Frequently Asked Questions
-
Will these pieces fit my child's Robotryx robot?
Yes. Every Extra Pieces pack is built from the same bricks as the Robotryx sets, in that Guardian's own colours — so they click straight onto an existing build with no adapters or workarounds. -
Do we need to own the robot before buying this?
Not at all. Plenty of families buy an Extra Pieces pack on its own and treat it as a free-build brick box. There is no single "right" model to make — that is rather the point. -
Are these the same bricks as the original set?
Yes — the same bricks and the same colour palette, plus the specialty connectors, joints and accessory pieces that give each Guardian its character. -
We lost a piece from our original build. Will this help?
That is exactly what these packs are for. You get a generous spread of the common bricks plus that Guardian's specialty pieces, so most gaps in a stalled build can be filled.
