S7·E13 The Renegades Strike

The Roadies motor to North Beach for a friendly competition of sand castle building. Upset that they are not at the beach to surf, Abe loses his cool and sculpts ""this mission sucks"" into the sand and sits and sulks. Josh and Sarah decide to team up and build a pierced nose as homage to their piercings. But in the end, Brian's ""Mayan Ruins"" gets him the prize. The rest of the day is devoted to surf kayaking, battle of the sexes style. Simple rules: whoever can catch the best four waves will win the prize. Abe, finally in his element, is pitted against Sarah in the final round. Sarah rides the biggest wave of the day but Abe walks away with the big prize. An elated Abe feels sorry for the way he acted earlier. The next day, while the Roadies are out looking for clues to their next mission, a renegade sneaks in and dognaps Menudo. Abe takes this as a personal attack, and the Roadies regroup to decide their next move.
