After fans dug into the lore they found out through a series of item descriptions and beta data the Naked Homer Simpson character was in fact gay. When Hidetaka Miyazaki was confronted by interviewers if he could confirm Naked Homer Simpson was in fact gay, he just smiled and said the fans could find out by looking at the boss fight closely. It turned out if you removed a piece of level geometry a rainbow heart could be seen with the initials H and S below. Thus confirming for once and for all Naked Homer Simpson was in fact gay.

Or at least that's what I remember from the 3 hour VaatiVidya video about it.

Great, there go another 60 hours in SotFS... THAAANKS!!!
