When the adults go hunting, the children at the camp are surprised by a strange boy, Walloobahl, who attemps to steal their food. As the children attempt to retrieve their food supplies, Walloobahl grows into a giant and escapes. On the next day, the leader of the tribe manages to stun Walloobahl who retreats into the scrub. The tribe finds a bark-lizard in his place and from then on name all bark-lizards Walloobahl.
