Megatron is convinced that Bulkhead is no longer a problem and decides it's time to take Soundwave for a test run. Optimus tells Bulkhead to give Sari a little time and space, saying that she still values her friend more than her toy, but Bulkhead isn't so sure.

Bulkhead destroys Soundwave, forcing Sari to use the Key to restore him, and he immediately starts up again. However, as she turns her back to Soundwave, the music-bot activates a cannon and targets Sari. (Even Tutor Bot does a little dance.) Bulkhead arrives, trying to convince Sari that something is wrong with Soundwave. Sari takes Soundwave and Tutor Bot to the park, where they have an impromptu concert, complete with garbagebots banging on their fellow garbagebots, and dancing humans. Soundwave's musical transmissions soon become powerful enough to control other Sumdac Systems automatons.which are pretty much everywhere. Megatron successfully uses Soundwave's weaponry and voice-modulation systems to make both Sari and the Autobots think Bulkhead is erratic, jealous, and dishonest. Bulkhead begins to see signs of Soundwave's evolving nature-"Did that thing just move by itself?"-but no one believes him.

Soundwave's systems were designed to grow and evolve when exposed to the Key eventually, Sari will unwittingly upgrade him into a suitable body for Megatron himself. Each dosage of the Key's power unlocks new features on Soundwave, making his musical light show more involved and impressive, and even more fun than plain ol' Bulkhead and the Autobots. When she inevitably starts to grow bored with her new toy, she uses the Key on it. As days go on, Sari pays less attention to Bulkhead and far more to Soundwave. Bulkhead tries to present Sari with his gift for her, a xylophone ( AIt's hard for Bulkhead to compete with that, and so, embarrassed, he slinks away dejectedly. When the Autobots arrive to help celebrate, the kids are quite happy to go play with the giant robots and leave the weird girl behind.

Sari's birthday party isn't much fun she has no real friends, the only attendees being the children of Sumdac Systems employees, who continue to be put off by her bad manners. He designs a new robot for Sari and tricks Dr. Megatron, monitoring events via security cameras as usual, notices both the power of the Key and the frivolous ways in which Sari employs it. They are able to defeat the bizarre villainess only after Sari uses the power of the Key to trigger a powerful sonic attack from the stereo systems in the toy store. The two of them are attacked by Professor Princess, who is on an ironically violent crusade to destroy violent toys. Bulkhead takes Sari toy shopping for her birthday (or "construction date" as he terms it), to purchase her something that makes the loud music she loves so much.
