The name never made sense to me. The "-ette" in Peachette comes from Toadette, not the crown. so Bowser with the crown should be Peachser or something like that. Maybe Peachowser?
@Hammlet Yea it doesn't make sense that way. It probably came from -ette being a diminutive suffix which is associated with femininity and therefore the object of desire; in short Thingette => Thing+Female => Thing+Sexy
poor waluigi...can't get any love...and yes I agree with Gus , I wouldn't mind getting squished by a thicc thwompette, girl be killing the thicc vibes.
