The MC Bat Commander has decided it's time to #BringBackTheAquabats, but he knows he can't do it alone. Without his fellow Aquabats to turn to, his first stop - The Wizard of Hollywood!

After visiting the Wizard of Hollywood and talking his way out of a parking ticket, the Commander rushes off to save Jimmy the Robot from his new job. Meanwhile, Silver Skull hatches a new plan to destroy The Aquabats.

Learning that Jimmy was sold by his former employer to a group of scavengers (depicted as an overt parody of Jawas from Star Wars), the Commander tracks them down in the desert and challenges them to a dance-off in exchange for his friend.

Failing the dance contest miserably, the Commander uses his mystical animal horn to turn the scavengers into Aquabats, thereby winning their support. Now rescued from the scrap heap, Jimmy informs the Commander that Silver Skull has been behind The Aquabats' separation. The two take off in the BattleTram to rescue EagleBones FalconHawk.

Tracking down EagleBones, now working as a waiter in a fancy restaurant, the Commander and Jimmy attempt to convince him to rejoin The Aquabats, only to be interrupted by the arrival of Powdered Milk Man.

Powdered Milk Man attempts to attack The Aquabats but is quickly subdued by Jimmy's projectile weaponry and some breakfast cereal. Now free from his restaurant job, EagleBones rejoins The Aquabats and they take off to reunite the rest of the team, unaware that Silver Skull is close on their tail. Guest starring Patton Oswalt as Mr. Efron/Powdered Milk Man.

The Aquabats catch up with Ricky, now an unsuccessful fruit vendor at the beach, but are intercepted by Silver Skull, who destroys the Commander's mystical horn and therefore their means to help recruit new Comrades. Their spirits broken, the remaining Aquabats nonetheless leave to find Crash.

While wandering about the desert looking for Crash, The Aquabats stumble into CobraMan and Silver Skull, who lure them into a trap to be destroyed by a ferocious battle beast.

After a brief fight, The Aquabats discover the battle beast is in fact Crash in disguise as part of his new job. The rest of the band convince him to rejoin The Aquabats and play a benefit show in Los Angeles to recruit more people into the Legion of Righteous Comrades. An emotional Crash, now grown to super-size, stomps on CobraMan and Silver Skull as the group departs. Laying weakened on the ground, the two villains are approached by ManAnt, who proposes an idea to ruin The Aquabats' benefit concert.
