I was recently told how Daisy's redesign was based on another character from Mario Golf. I had no idea, but check this out (for those who didn't know already):
From her debut in 1989 to Super Smash Bros. Melee in 2001, Daisy looked like this:
Towards the end of this period, in 1999, Mario Golf for the N64 marked the debut of
Azalea:
Azalea appears to be a tribute to Daisy, what with her physical appearance, being champion of the Dunes course, oh and the fact that in Hebrew, Azalea means "Flower" and in Greek Azalea means "Dry". But notice her shoulder-length, flipped back hair, a fairer complexion, and the use two shades of orange in her clothing, because these were incorporated in Daisy's redesign beginning with Mario Party 4 in 2002:
Neat, huh?
So what about Azalea, who hasn't appeared since 2004? Since Azalea never appeared in a game alongside Daisy, could they be the same person? Perhaps Daisy went by a different alias during a phase? Or is Azalea Daisy's long-lost sister (apparently Daisy and Peach are cousins)?
Or else if you don't believe in internal consistencies than it can just be noted that the two characters merged.
