So, who was the one that was in labor when 1up was born?
Peach, haven't you played the flash games?
Jkjk.
wait.....so if 1up is peaches baby....then she must have cheated on Mario with Toad because the 1up shroom sure as hell doesn't look like Mario one bit.....but its green.....a 3 way with toad and Luigi causing both to impregnate for her to give birth to a mutant oof a creature we today know as 1up....and NEITHER of them pay 1up child support either....
