One penguin? Nope, four penguins! These charming Matryoshka figurines are always great for a nice surprise. The lovingly painted wooden Papa Penguin houses the whole family. In addition to being stackable, Mama Penguin and the two baby penguins can also be lined up according to size along with Papa Penguin. These Matryoshka dolls are great for hand-eye coordination and fine motor skills, and they also look simply cute!
