How does a frog grow? With this cute, sturdy puzzle, young children can learn about the frog's life cycle while having a great time. Start with the tadpole in a "pond." Add pieces as the frog slowly grows and end up with a perky wooden frog smiling from atop a green lily pad. The base for each life stage is made of ecofriendly PlanWood, with a tadpole and a frog made from solid wood. Children play happily while developing hand-eye coordination and fine motor skills. Base dimensions: 7.6 in x 5.9 in x 3.4 in.
