Universe L (Jenny Everywhere and the Lord of Hell)
One universe where Jenny Everywhere existed resembled the kind of world usually depicted in short vintage ads in comic books; a salient feature of it was a park where children played, and could occasionally be attacked by villains who could only be repelled by the “power” of Stewardess® Fruit Pie.
Another Jenny briefly shifted into this universe while trying to defeat Lord Grallyx, taking him along with her so as to retcon him into the fabric of that universe. Due to becoming a part of that world, he became weak to the power of the Fruit Pies. Jenny took note of this and, after they shifted to yet another universe, made use of this same principle in yet another dimension to defeat Grallyx at last.
