Remember, Iím a trained professional!
The Snake Charmer is a real reptile expert. He likes lizards, adores alligators, and heís crazy about crocodiles, but what he really loves are snakes. He takes excellent care of his cobra, making sure that sheís always kept at the correct temperature and fed the right foods, and in return she helps him to entertain audiences with their celebrated snake-charming act.
All he has to do is play a tune on his pungi flute, and his cobra slithers, sways, and dances to the melody. It may look risky, but the Snake Charmer has had lots of practice, and heís very careful. He isnít completely fearless, though Ė he hasnít yet worked up the nerve to ask Medusa out on a date!
