This bundles includes the five primary animal puzzles (Bird, Turtle, Horse, Fish, and Frog) at more than 10% the price of purchasing them all separately!  These animals are commonly used together because they represent the five major classifications of animals: birds, reptiles, mammals, fish, and amphibians.  The Animal Nomenclature Set (sold separately) is the perfect companion for learning the parts of each animal, and the Five Puzzle Cabinet (sold separately) is an ideal storage solution.
