The Biskitts meets Dogfoot while Downer is sick. King Max uses the Trick Book to get the treasure. Unfortunately, Sweets and Downer are on the treasure box at the time. Wags and other Biskitts must get the treasure back and save Sweets and Downer.
King Max and Shecky search for the Biskitts and attack them suddenly. On Halloween, a witch that the Biskitts have outsmarted years ago returns to capture two Biskitts in order to stay on Biskitt Swamp. Her spell ends up draining the life out of the swamp which also turns Scratch, King Max, and Shecky into stone. She kidnaps Waggs and Sweets. Now the other Biskitts must save them before the witch's spell is complete.
Snarl gets hurt and the Biskitts take care of him with Shiner being the biggest helper. A Black Knight appears and he is after the Biskitts' treasure so he kidnaps Scat. Now the Biskitts and King Max have to work together to thwart the Black Knight.
