There are two distinct versions (different color phases and poses) of each of 11 small mammals that generally live in grasslands, along creeks/ponds, or woodland edges of Midwestern habitats: Eastern Chipmunk, Franklin's Ground Squirrel, Eastern Mole, Plains Pocket Gopher, Thirteen Lined Ground Squirrel, Northern Short Tailed Shrew, Southern Bog Lemming, Meadow Vole, Meadow Jumping Mouse, Deer Mouse, and Northern
Grasshopper Mouse. A set of card fronts and backs gives facts about each of the animals (to be matched to the corresponding jointed models) with an image of the correct animal on the reverse side for self-checking.
