Credits and indicia for the issue. Color on inside front cover.
The primary summer camp sequence is introduced by the title "Morty and Rick in: Mortballs (cue music)" - a title parody of the 1979 Bill Murry comedy movie "Meatballs".
Much of the rest is a parody of/tribute to the 1984 horror movie "A Nightmare on Elm Street", which introduced iconic horror film character Freddy Krueger - suggesting the unofficial title.
Oddly, "Our Beth" is not the leader of this band that exists in her image, but just one of the band-members. Perhaps all of them are Beths gathered from different realities.
