Colors included
Based on this tube's colors, these builds and videos should be possible.
These builds use your tube colors as substitutes when the original colors are missing.
The Mecha Bot tube is a character-led Plus-Plus set for builders who like action, costumes, and imaginative role play.
With 70 official pieces in 6 colors (Red, Yellow, Blue, White, Grey, Smoke), the palette supports armor, faces, props, and bold silhouette shapes.
Follow the flyer to build a Mecha Bot, then study how color placement brings personality to even simple block forms.
When the star model is done, the same pieces can become allies, vehicles, bases, and comic-style 2D scenes.
The reusable tube format makes it easy to pack this world into a backpack and keep building anywhere.
Suggested for ages 5+
