Tough question, I'm actually going to say Harold.
He help win the DodgeBrawl, the talent show, attempeted to face his fears, jumped off the cliff, collected 5 flags (even if he lost them by seeing Heather's bra flying off) and gave everyone hope (or tried to).

In challenges, he deserves to win.

Yep coolguy11606 is 100 percent correct. Nomatter
what anyone says, Harold is the best.

You can just call me Coolguy.

The only other person who is in the running is Justin.
- Jumped off the cliff, missed the target, but the sharks brought him back to land.
- Painted his eyes in the Awake-a-thon, till he was caught by his own teammates.
- Got 7/9 star rating in the Talent Show, the 3rd highest score.

Yep, Harold accomplished the most. (and even saw Heather's shirt flying off (:}))

maybe after harold gwen or leshwana
