Shock and Jessica are teaching kids how to beatbox until Manny blasts his radio so loud that it annoys the patrons at the diner, including Hector. Manny says he can find a better beatboxer than Shock, then Hector bets his power on it. But there's a problem, Shock refuses to compete. He remembers the last time he did was many years ago when he met a kid named Wiki Wiki Walter. Wiki taught him how to beatbox until he broke off their friendship after losing to Shock in a beatbox battle by another kid. Meanwhile, Manny is holding auditions for people who beatbox until someone shows up. Hector and Shock get a call to see a grown Wiki with Manny telling Shock to step up and battle him. Shock decides to compete again. Hector's power is on line with no turning back because he pinky-swore to Manny. Shock and Wiki both train for the beatbox battle. Hector trains Shock while Manny has his robot battle Wiki for practice. At the time of the battle Shock and Wiki meet face to face for the first time in years. Host Doug E. Fresh starts the first round with sound on sound. Shock messes up and loses the round to Wiki. On the second round which is the tempo, Shock beats Wiki on triple-time. Shock considers quitting but Hector tells him to win it or he'll lose his power to Manny. In the freestyle round, Shock teaches Wiki to beatbox just like the old days. The audience voted on both men which led to a draw. Shock and Wiki are friends again, and Hector keeps his power.
