Some Idiot Forgot to Finish His Challenge Run (Super Paper Mario Damageless - Part 15)

So, uh, I kinda forgot to finish this challenge so hopefully let's get it done tonight! Rules for this challenge: No taking damage. I have a cheat code that makes any damage just kill me. If I take damage and the cheat code doesn't account for that, I will restart manually No using items, I feel with stuff like the Block Block that would trivialise the challenge Life Shrooms but be consumed immediately however, since the do nothing unless we die with them in out inventory Savestates are only allowed at save blocks, or after long cutscenes that I have to watch over and over if necesary. Just to save on time and my sanity. No major glitches or skips, because I don't know how to do them.
