Unfortunately this reign of pink began a thousand year war of blancmange. The viscous stuff was everywhere, and covered everyone, creating a new super-race, the creatures from the deep blancmange.
Unfortunately Glargablorg, hero of a million multiverses, noted that the all the world has become complacent with regards to sickness and plague. He begins selectively evolving his new virus that was able to overcome these strengthed immune systems to unleash upon the world and defeat all those that would oppose him, particularly Barbie. Allowing him to rule the creatures of magic and claim the rings of fortune.
Rings, you say? Fortunately, Midge the Merciless never met a ring she didn’t like. You know Midge, right? Barbie’s gal-pal? Mounted upon her mighty Megaloceros, cloven hooves striking sparks from the fundamental matrix of matter, she rides in filled with fury. She’s also got a thing for alliteration. No one’s perfect. She presses her steed forward. Behold, chaos is upon the land.
Fortunately, Barbie (who had been able to save both herself and a remnant of humanity from Glargablorg's plague using her vast medical expertise) saw how both Midge and Glargablorg were willing to do anything for the rings of fortune. She accepted the new career set for her, leader and protector of the free people of earth, and began accumulating allies and resources for the fighting of these two threats
Unfortunately, Schwarenegger was still spending his immortal life educating people on how to stay safe from the plaque, and thus didn't have time for Barbie's war of the rings
Unfortunately Barbie had evolved into a being beyond our mere mortal understanding and she suffocated Joe in an eldritch ooze of pure pink. What is pure pink? You don't want to know.
