Your toddler is going to love building our Underwater Adventure, using 42 big building blocks. They can place the adorable Peek A Blocks turtle or shark on the octopus and the other on the launcher, then press down on the lever to send the Peek a Blocks down the slide for 1 of 2 rolling surprises - either passing through the fish flap, or through the octopus to get it spinning, launching the other animal down in the opposite direction. Ideal for First Builders, ages 1+
