Una travesura prehistórica

Like Mona Sapiens, inventor (although she never gets it right the first time); Crok Mañón, the strongest boy of all (and also the most brutal), and Pepe Saurio..., the only one who has nothing special. At least, until he gets Mona's magic potion on him, which turns him into a dinosaur. Achu! Except when he sneezes... and he goes back to being a normal boy. In this first adventure, Pepe and his friends will have to face the Cave Monster. A monster that is not what it seems.
