The Scooby Gang is invited to the Forbidden Forest by Dr. Norbeckenstein, (the owner of the Fan the Flicker Bed and Breakfast) whose guests are being scared off by rumors and sightings of a giant scary monster in the woods. The monster is not only caught but found to be actually a kindler gentler monster that thought he needed to be bigger and scarier to be accepted. He learns to accept how God made him and everyone lives happily ever after.
Based on Moses at the Burning Bush and his not thinking he was good enough for what called him to do.
