Which Lego Duplo sets offer the most pieces per set?

LEGO DUPLO My First Creative Vehicles (10474) lets toddlers build multiple vehicle models, including a helicopter with a spinning rotor, a dump truck with a tipping bed, a fire truck with a hinged ladder, and a small family car. Kids then pull apart the bricks and combine them with extra pieces to create new vehicle builds. It is aimed at very young builders learning early fine-motor skills through simple, hands-on play.

Toddlers can build and rebuild 3 modern home layouts in one set, including an apartment layout or a multi-story dollhouse with a roof garden. The set includes 4 figures (2 parents, a toddler and a baby) plus familiar accessories for pretend family routines and storytelling. It's designed for social-emotional play and fine-motor skill development for young builders.

This LEGO DUPLO brick box (10439) includes 80 pieces and 3 wheelbases to build vehicles like a race car with podium, a tow truck, and a family car. It's designed for toddlers aged 18 months and up using simple picture instructions. The set also includes a mechanic, a child, and a bee figure for imaginative play.
