Spooksville - The Creature in the Teacher

School has finally started in Spooksville. For Adam and his friends the first day is disturbing. Their science teacher seems to be an alien monster! He is some weird kind of reptillian creature from another planet. A creature who not only grades hard, but eats his students as well. At least this is what Adam and his friends think. The alien must be evil. He must be destroyed. Unfortunately, their science teacher is not so easy to stop!
