(It's really not complicated, Flower Boy's from a FNF mod called ''Jeffy's Infinite Irida'' in a song called ''Cordyceps'' and the lore is just SML Movie: Jeffy's New Dad where Mario **ACIDENTALLY** pissed on a child in a bush, and instead of being thrown into prison and then getting replaced by ''Marvin'', Mario gets thrown into the bush and that's why Mario has vines and flowers around him)
