The caveman clan needs a new chief! Gather 'round to perform the sacred chant known as "Ooga Booga". As the voices of the tribe rise into a side-splitting song, the sharpest memory will determine the leader of the pack. In Ooga Booga, each card has either an ancient word or wild gesture. With pounding fists, absurd grunting, and outbursts of laughter, Ooga Booga gets homo sapiens of all ages to shed their modern inhibitions and join in the prehistoric fun!
