Bring a mechanical creature of the deep to life
Build an extraordinary fusion of nature and machinery with the MJI 13085 Semi-Mechanical Octopus building set.
Constructed from 1,768 interlocking pieces, this detailed model reimagines an octopus as a complex mechanical creature with segmented tentacles, exposed gears, articulated joints, pipes and layered armour panels.
Once assembled, the model measures approximately 36 × 32.5 × 31.5 cm, creating an impressive centrepiece for a desk, shelf or display cabinet.
Motorised mechanical movement
The included motor powers the internal gear-and-linkage mechanism, bringing coordinated movement to the octopus’s segmented tentacles.
The mechanical system combines rotating gears, axles and linked components to create a dynamic moving display. The articulated tentacle construction enhances the model’s biomechanical appearance while demonstrating how multiple mechanical elements work together.
Integrated lighting
Built-in lighting adds an atmospheric glow to the completed model and highlights its mechanical body, exposed components and display structure.
Combined with the moving tentacles, the illuminated details transform the finished build into an eye-catching mechanical display rather than a conventional static construction set.
The combination of organic curves and industrial detailing makes this set ideal for fans of mechanical creatures, robotics, science fiction and steampunk-inspired designs.
The set is supplied unassembled and includes an illustrated step-by-step building manual.
