MEGA BLOKS 3-in-1 builds for preschoolers
Our 3-in-1 sets are the step up for children who are ready to follow a picture guide. Each box holds around twenty-five big blocks and simple building steps for three models: a unicorn that turns into a puppy or pegasus, a kitten that becomes a fox or lion, a race car that becomes a pickup truck or hot rod, a chomping T-Rex that becomes a pterodactyl or dragon.
They sit on our 3+ shelf, roll on their own wheels and still use the same big blocks as everything else here.

Three things parents ask about this shelf
Can a three-year-old build it alone?
The steps are drawn for preschoolers, and the blocks are the same easy-grip size as our toddler sets. Most children need a grown-up for the first model and then take over.
Do the three models need extra pieces?
No. Each set rebuilds all three models from the blocks in its box.
Which one should we start with?
Pick the creature or vehicle your child already talks about. Building is easier to stick with when the finished model is something they love.
