Manfred the Wooly mammoth (Ray Romano) and Sid the Sloth (John Leguizamo) play a game of charades with their little furry squirrel friend to see what happened to the humans.   In this CGI 'toon, a saber-toothed tiger (voiced by Leary) and a wooly mammoth (Romano) are among the friendly animals who try to reunite a lost human baby with its parents, apparently unaware that the humans are gonna take over and maybe they shouldn’t be giving them so much help.
