Princess Nebula, an air-headed medieval princess, makes her bid for fame as a contestant on Skatoony. But the simple act of discarding a snotty hanky has dire consequences...like causing TDI's Owen, a nervous, compulsive overeater, to go to town on the Quiz Block. Chudd retrieves the hanky for his used hanky collection, but the jealous knight Sir Rudolf challenges Chudd to a duel. Chudd must defeat the Knight in order to get the show back on track and crown this week's Skatoony champ.

Despite employing underhanded tactics, Zeppo the alien overlord's high-tech cheating equipment lets him down, causing him to be booted out in the second round. Filled with rage he declares that if he can't win Skatoony, no one can, including Noah, Total Drama Island's resident know-it-all. Zeppo is then forced to bring in his most powerful spaceship to destroy his carbon-based contestants. Can Chudd and The Earl stop him in time to play the Skatoony Quiz Champ Challenge?

Bigfoot is very excited about this week's Skatoony Quiz. Unfortunately this causes the lovable lump to emit a sinus-frying stink strong enough to knock over TDI tough-girl, Eva. With the unbearable smell putting off the other contestants, it's up to The Earl to clean up Bigfoot's bog-like odour and put the quiz back on track. To add to the problems Bigfoot and Charles both fall in love with fellow contestant, society rich girl Penny Posh-Botts. A love triangle forms and it's down to Chudd and The Earl to break up the fight before the final Skatoony Quiz Champ Challenge.

T-Bone and his Skeleton Crew, which includes newest member Harold (who joined the group after T-Bone saw him beat-box on Total Drama Island) make a special guest appearance on Skatoony to promote their new hip-hop album. However problems arise when Charles' Granny arrives and finds their rowdy behaviour utterly unacceptable-bad news for Charles. It's up to Chudd and The Earl to keep Charles' Granny unaware of the outrageous goings on or risk Charles' wrath. But as the quiz progresses and The Crew gets carried away, Chudd and The Earl resort to increasingly desperate measures to keep Granny's mind on other things.
