Synopsis:

After unmasking "The Bog Beast" in some mucky swampland, the gang takes the slime-covered Mystery Machine to a car wash. As the van moves through the sudsy water-pressured works and great whirling brushes, Scooby spots a tentacled, cyclopean brush monster dubbed "The Clean Fiend". A second run through the wash proves the existence of The Clean Fiend to the rest of the gang, who characteristically vow to get to the bottom of this mystery.

Good Bit of the "Surprised-They-Got-Away-With-It-Variety":
SHAGGY (upon first seeing the brush monster through the soapy waters): "Zoinks! It's The Clean Fiend! Like, it SUDS to be us!"

New story.
