So since the tears wouldn't really exist in this world I've have to make something up for Peach to be able to use.
These are corruption pieces created by the Chaos Heart. They're seen floating around Count Bleck's Castle. They are made of the same destruction of the Chaos Heart.
And a single touch from them can lead to them being erased just like what The Void is doing to the Worlds.
(We're trapped...No way out.)
(Mario says we'll find a way.)
(But we all know it's not true.)
(But...There is one way.)
(A way only you can do it.)
(It HAS to be you!...You're the Princess.)
(Pay no mind to everyone.)
(You're doing this for them.)
(For everyone. You NEED to do this...Since Only you can do this.)
(You NEED to start the loop again.)
(You ignore everyone's screams.)
(You touch the courruption.)
(It hurt when you touched it.)
(But it's fine.)
(It's fine!)
(It's alright! Everyone won't be trapped!)
(You'll choose the right way this time!)
(And it'll end up alright in the end.)
(You'll go through whatever kind of pain to save them.)
And here's Rena which Peach meets after her first loop. She meets them at the first Heart Pillar when she wants to be alone and think about everything that just happened and sees them sitting on top of the Heart Pillar.
This idea just came into my head so I'd thought I try it. So basically this happens during Super Paper Mario when they're getting ready to head into Count Bleck's Castle. Peach decides to make a wish due to her connections with the stars and wishing.
When they enter Count Bleck's Castle has a lot of traps then in the original and well. Mario accidentally activates one and Peach pushes him out of the way and she dies.
Then she wakes up back in Flipside. With everyone saying things that Peach has already heard before and none of her friends remember that she died.
