Although BrawlEx is able to make it so each costume has its own Entry file, it's actually a lie because the game will use the same file for all costumes when loaded. The setting only exists because Peach has Entry files for each costume however they are duplicate files, so the entire feature is pointless.

To work around that, I've replaced F.L.U.D.D. with the Entry model & animations. Project M already doesn't use F.L.U.D.D. so it works out perfectly and makes it so the Entry is easily customizable for each costume without even needing BrawlEx or heavily increasing the file size. It's a win-win.

In addition, the Fireball & Pills used during the Down Taunt are also part of this model, this is so each costume can their own version without making the FitMario.pac insanely big. The Doctor slots randomly select from AnimationData[2] through AnimationData[11] (excluding AnimationData[9] because that one breaks) during the Down Taunt in order to have a random colored Pill. The other slots only use AnimationData[2] but can be used over a Doctor Slot without edits because the other 8 Redirect (Reuse) AnimationData[2].

If you know your way around with BrawlBox/Crate, I've also included the separate models for you to Mix and Match the Entry models & Projectiles.
