I do NOT know who the original author for this pasta is, so if you're him/her, give me a shout!
While I admit that this particular pasta was a little overplayed, gore wise and all, it's still the best of the bunch of Luigi's Mansion pastas I could dig up...
...Yeah, I do have this creepy ass Luigi slipper. Which I actually DID find staring RIGHT at me after I was done reading the Luigi's Mansion Beta Disk pasta. With the Mario slipper far over to Luigi's left side on its back. Oh good. :'D
