Like Mona Sapiens, inventor (although she never gets it right on the first try); Crok Magnon, the strongest kid of all (and also the brutest); and Pete Saurus..., the only one who doesn't have anything special.

At least, until he gets covered by one of Mona's magic potions, which turns him into a dinosaur. Achoo! Except when he sneezes... and he turns into a normal kid again.

In this first adventure, Pete and his friends will have to encounter the Monster of the Caves. A monster that is not what it seems.
