These unique wooden puzzles have children putting the puzzle pieces into the frame in three sequential layers to tell a short story.

This beautiful puzzle shows the life cycle of a frog. Bottom Layer: A frog has laid eggs at the bottom of a lake. A tiny tadpole is growing inside each small egg. Middle Layer: After the tadpoles have hatched, their front and back legs begin to grow. Top Layer: Now the frog is almost as big as the water lily on which he is sitting.
