Lady Finger 4
LF4 was a Neopets user who messed with the FC boards by linking random userlookups and petpages like a crazy person. They made everyone think it was some kind of secret code, but it was just a stupid joke that made people go insane.
Check out this userlookup, it's totally part of the codec! (it wasn't)
This petpage is a clue, I swear it is!
I'm gonna decode this or I'll die trying.
