He wanted to scare Jebediah Johannsen and his family away, so that he could steal the secret recipe for the very delicious chocolate made by Jebediah Johannsen.

Bob Fingerman must have seen seen Willy Wonka and the Chocolate Factory. He must know what horror from a children's tale can achieve. Gene Wilder portrayed one of the most sinister figures in children's literature. Although a musical, the movie lost none of its threat. Think The Phantom of the Opera was the first to mix terror and music? Think again. So what do we Scooby fans get? A demonic, purple clad candyman? A scar-faced Erik? No! We are given a saccharine "faux" ghost who allegedly drowned in a chocolate vat! This is beyond weak, and quite frankly you would think portable stomachs like Shaggy and Scoob would overmatch this particular "spook," but for some reason the dynamic digestive tracts are afraid of a guy covered in chocolate.
The tantalizing odor of the sweet drawing Daphne and Velma toward the barrels of glop suggest they like the euphoric feelings induced by endorphins just like any other normal gal, but this subtext and the damn cute depiction of Daphne in the finale cannot save a very stupid story. Just out of curiosity is there any reason why the Amish needed to be here? Apart from providing the ridiculous clue, I think not!
