Description Another family has moved into the house at 666 Duende Street across from Vincent Ventura's, and once again there's something mysterious going on. There's a boy who constantly argues with himself. "You can't tell me what to do," Vincent hears him say, but there's no one around. Who could he be talking to? When Vincent sees a green creature with glowing red eyes and needle-sharp teeth terrorize the boy into vandalizing a neighbor's car, he knows there is another monster mystery to solve!
