What if you could add a Pixl partner to TTYD as a partner, with a bigger backstory?
I’d add Dottie. Her shrinking ability makes Mario crumple into a very tiny paper ball, which can roll into very small spaces, sort of like the tube, but for very teeny holes and stuff. Any tiny bit of wind sends him flying way back. You meet her in Chapter 2, and the Boggly Tree has a new mechanic where you occasionally have to compress into ‘Puni paper’ and solve puzzles on the Puni’s level. You even get to fight through the Jabbi and enter their bases yourself.
Her craggin tragic story: The Floro Sapiens from SPM join the X-Naut invasion of the Boggly Tree, trying to destroy it by planting themselves at its roots, and Dottie wants to help you beat them, because they already took over her original world.
