Tropes
Throw It In!: Crash X Fusion indirectly inspired the new A-plot; he never considered the chapter would be set in the Human Realm, but both authors became intrigued by his prediction of Serpentina summoning a sea monster and rolled with it, having LOWTH battle the beast which made up the new A-plot.
What Could Have Been: The chapter was originally focused on Luz's group having their beach day in Echo Creek, but upon being given the idea to have Serpentina use a sea monster to attack the Isles, the writers included a new plot with Luz's group becoming the stars of the B-plot.
