It's Leo's job as the Guardian's apprentice to protect the village from the monsters that lurk in the surrounding forest. Whenever a creature gets too close to the settlement's walls, Leo must venture out, using his magical map to first find the beast, and then do battle with it. This time, Leo must track down a deadly Spitfang Lizard before it reaches the village. He is given one piece of advice - first they spit, then they bite. If a Spitfang's throat swells up . . . run!
