The incredibly loose framework of the Bizarro World stories (such as this one from Adventure Comics vol.1 No.290) meant that more than reason was thrown out of the window. Daffy characters and conflicts troubled the equally-daffy homeworld every month with little rhyme nor reason, albeit with great energy and enthusiasm.
Above, for instance, some forgotten characters whose existence and end were never fully examined: Bizarro-Hipster No.1 (he was into it before anyone else, as evidenced by his number), Weep-And-Wail Bizarro Lois and the Bizarro Cool Cat Combo create alarming jazz numbers and tone poetry into order to celebrate the appearance of genocidal blue Kryptonite monsters, dedicated to destroying Bizarro World.
Who are the Blue Kryptonite creatures? Where did they come from? What do they want? Where did they go? Why do they have brain heads and weird veiny bodies? And where have all the Beatnik Bizarros gone? Wouldn’t Beatnik Bizarros actually be squares? What’s going on here? I have no idea, and I guess it isn’t terribly important in the grand scheme of things.
