A marble run that builds up a wall instead of across the floor — 216 jungle-themed pieces for a baseplate or board.

Designed to build on a DUPLO®-size MagicPlate or the JBOARD building board.

✦ 216 pieces — 130 foundation blocks, multi-directional chutes with curves, drops and funnels, plus jungle animals and trees

✦ Vertical, not flat — building upright is a different problem from building on the floor, and the finished run is visible across the room

✦ Try the slow-mo challenge — build the longest track that keeps the ball moving as slowly as possible without stopping; that's friction and incline, learned by playing

✦ Mixes with the gear set — combine with the JBRIX Gear & Peg Construction Set for builds neither set makes alone

✦ Jungle theme — animal figures, trees and decorative pieces bring the run to life

WARNING: CHOKING HAZARD – Small parts. Not for children under 3 years.

1. Is this set compatible with my existing Duplo baseplate?
Yes! designed to be compatible with Duplo baseplate. Joykids Double Sided Board (Duplo) & Magicplate (Duplo)

2. Can I combine this with the Gear & Peg Set?
Yes! In fact, we highly recommend it. You can use the STEM Gears to create "rotating gates" or "mechanical lifts" for your marble run. Mixing the two sets allows your child to build complex, interactive engineering walls.

3. Is it easy for a child to snap the pieces on?
Yes. The pieces are designed for "large-block" compatibility, which is specifically engineered for smaller hands (ages 3+). It helps develop fine motor skills and hand-eye coordination without being frustratingly difficult to assemble.
