Ok so, to go further in to the theory of "Pink is going to be the weird route final boss"
The whole lyrics of Cutie Mew Mew Magic seeming to be about the weird route and Mew Mew saving the day
In the switch undertale port trailer she breaks out of a chunk of ice!? And since Mad Mew Mew and Pink are the same....
The Parallels between Kris and Pink are clear. And many would say Pink is the best outcome. Wouldnt it make sense For the best outcome of our relationship with Kris be our final challenge on the road of the worst version of that relationship
You also skipped the dark world in chapter 5! In every other chapter you can fight the boss so it would make sense you fight her too
And I think that's why it is possible that Pink is the final boss
