After being reunited with Schneider 6689, Davey and Jonesie are finally ready to go back home and face the music of the mess they left behind. But when Schneider tells them that the conditions have to be exactly the same as when they initially left, the girls realize there's one small detail that's different... they don't have the mascot heads from their protest. But maybe that's actually a good thing! With the mascot heads mysteriously missing, no one will be able to prove that it was them who ruined the dance and Principal Neighbors won't be able to separate them. With that, the girls tell Schneider that they're ready and he resets the universe manually. Their angry classmates and Principal Neighbors rush to the girls and accuse them of ruining the dance and stashing the mascot heads in their locker. The girls feign innocence and open their locker to prove that it wasn't them, but a giant spider leg bursts through just as other parts of different universes start to appear. Schneider berates them and explains that resetting a world that's been deteriorating in stasis for so long with some of its matter missing will cause elements from different universes to seep in. To save their universe, the girls own up to their mistakes and ask their friends for help to hoard all of the anomalies back into the locker. Meanwhile, an enraged Cheryl comes after them, forcing Schneider to face his past.
