Season one[]
Shaggy Rogers, Scooby-Doo, and Dynomutt attempted to photograph plans from the criminals Swamp Rat and Mudmouth, instead of calling for backup once they found the place, as instructed by Blue Falcon. Their disguise routine quickly fell apart, and they were captured and used as bait to lure everyone into a death-trap.
