Things you didn't notice before in Mario games

Daisy's earrings used to only have five petals on them.
 
There's something off about Birdo's model in Double Dash, compared to her models in other games. I swear there's something off with her bow, but I just can't place it.
 
it's the size , i think

Her model was one of the few models altered a bit to be reused in MKWii , along with King Boo and Donkey Kong i think
