Description

Three dinosaurs from one set

What sets 10451 apart is its 3-in-1 concept: the 108 pieces can be rearranged into three different dinosaur models, each built on wheels so they can be pushed and pulled around. Lime, medium azure, dark turquoise and reddish orange spread across the different models, giving each one bold, easy-to-tell-apart blocks of colour typical of Duplo sets. Large, easy-grip bricks and simple connections make switching from one model to the next manageable for small hands, without much help needed from adults, and each model has its own distinct shape that makes the rebuilding itself part of the fun. Rounded shapes throughout also help the models hold up well to enthusiastic, hands-on play.

Built for early building skills

With 41 unique parts across 108 pieces total, the set sits in a familiar Duplo range: big enough for variety, simple enough for young children to manage on their own. The wheels on each of the three models add pushing play on top of straightforward building, which goes beyond simple stacking and helps develop motor skills. Since there are no minifigures in the classic sense, the focus stays entirely on the dinosaur models themselves, and rebuilding the three versions repeatedly gives children a natural reason to keep coming back to the set.

Colours, rebuilding and combining sets

The bold colour palette of lime, medium azure, dark turquoise and reddish orange pairs well with other Duplo sets, such as existing animal figures or vehicles already in a collection. The parts list on this page lists all 41 elements along with their colours, handy for parents checking which pieces belong to which of the three dinosaur models or hunting for matching additions, and because there are no minifigures involved, the focus stays consistently on building and moving the dinosaurs around. For parents, the 3-in-1 approach is also a simple way to keep a single set interesting for longer.
