Junior biologists can create an unlimited number of creeping creatures, from slithery snakes to stalking crocodiles to creatures of their own imagination, with this building kit. Like a puzzle and 3-D construction set in one, unique foam and plastic pieces link, stack, and rotate to form any imaginable cold-blooded (or "ectothermic") animal.
