MJI Mechanical Piranha

The MJI Mechanical Piranha is a hands-on mechanical building kit that turns creative assembly into kinetic display art. This set includes precisely fitted pieces and an illustrated instruction booklet so you can build your own articulated piranha model from scratch. Once completed, its mechanical components interlock to create lifelike movement and structural details, making it both a fun project and an eye-catching tabletop piece. Like others in the MJI range, this model encourages fine motor skills and problem-solving as you explore how gears and linkages work together to animate your finished build — perfect for hobbyists, collectors, and anyone who enjoys mechanical puzzles with a marine twist.

Key Features:
• Interactive mechanical motion in multiple movable parts (tail, fins, jaw) once assembled.
• Precision-fit building pieces with smooth edges and clear instructions.
• A satisfying DIY engineering project that also doubles as a decorative centerpiece.

Good to Know:
• Recommended for ages 14+ due to small parts and mechanical complexity.
• Batteries and motors are optional extras for enhanced movement or lighting (not included in some versions).

McMerwe’s comments: More than just a toy, this puzzle-style kit encourages hand-eye coordination, problem-solving, and patience, making it a great gift for teens and adults alike.
