Overview

Discover a hands-on building experience with the Unasas Marble Run set. This 121-piece construction system invites kids to explore marble pathways while bringing three large dinosaurs and three small dinos to life. A tiny house and a playful figure add narrative spark, turning engineering challenges into lively, imaginative play. The durable blocks are designed for enthusiastic use and can grow with your child as they experiment with speed, angles, and pathways.

Interactive play that blends storytelling with engineering

Kids can construct marble tracks featuring three large dinosaurs or craft scenes with three small dinos, while the included house and figure encourage cinematic storytelling alongside spatial problem-solving. The setup invites hands-on exploration of cause-and-effect as marbles race through curves and ramps.

• Includes 6 dinosaur figures (3 large, 3 small) and a house for storytelling play
• Two baseplates provide sturdy foundations to anchor designs
• Modular bricks expand with your existing collections for endless creativity
• Illustrated, progressive guide supports a clear path from starter to advanced builds

Growth-friendly design and safe construction

The set is built from thickened ABS plastic with rounded edges to promote safe handling during energizing play sessions. The dinosaurs’ eyes are molded-in for added safety.
