The story: A wooley mammoth from the Ice Age is thawed out in the 20th century by Dr. C and Mikey. Each episode, he tells a story about his caveman friend, Cro. Each story has to do with science in every Stone Age daily life. The show premiered on PBS kids in 1993 and then was taken off the air in the summer of 1995. The show was later reran on Noggin (now Nick Jr.) from 1999-2002. No doubt if the show will rerun on PBS Kids Sprout.
