Jigglypuff with her Red/Pink bow from later Smash games! This is an updated version with an actually good CSP and a couple general improvements. Have fun!
MexTool: Import PlPrPk.dat as a new costume, then import the CSP and stock icon. Make sure you create a filesystem first!
DAT Texture Wizard: Replace the PlPrBu.dat in your game’s iso with the PlPrBu in this download. For the CSP and stock icon, export IfAll.usd and MnSlChr.usd, replace the stock icons and CSP portraits in those .dats, then reimport.
