So, about the changes to Peacock's palette. She has the Kuribo Shoe and Bullet Bills, Tommy seems to be a Thwomp, her teeth are white like the Chain Chomp's, her grab appears colored similar to the Snag Bag, George Car seems to mimic Daisy's vehicle in Mario Kart, her beam and Argus Eyes are green (Daisy stuff usually has green somewhere). Couldn't find any other references. The Bob-ombs are pink-ish, which is weird. I know there are pink bob-ombs, but when I think Bob-omb I usually think the other ones, like black-ish/purple-ish/blue-ish.
Bob-omb buddies seems more appropriate given how Daisy is considered to be good-aligned
However, right now I will let the Mario fanatic inside me take over for this post.
Item drop whistle could easily pass as the Warp Whistle from SMB3 instead of a black one like it is now.
George's plane is green for some reason, when Sky Pop that Mario flew to save Daisy from Tatanga was yellow.
Andy Anvil could easily pass as a Broozer
Avery's color doesn't really seem to be anything other than a yellow bird with a yellow outfit, although he could pass as an Albatoss from SMB2 pretty easily.
The smoke that appears when Avery disappears or the from the drag of her cigar have faces on them. Other than in chapter 6 of Paper Mario, non-enemy clouds with faces on them have always been white.
Also I know I had a gripe about her ribbon not attempting to reflect Daisy's brooch but the argus eyes are deliberately colored to reflect it so I'm not too perturbed.
Okay now I'm done nitpicking about shit that bothers me and only me.
EDIT: Nope not done nitpicking.
Peacock's arm segments are orange for some reason, Daisy's never had sleeves when wearing a dress so her skin is bare there.
The hammer in her jLP is black for some reason. If it's to mirror the Hammer from Donkey Kong that appears in the Smash games, the handle is erroneously green instead of wooden.
If Tommy's supposed to be a thwomp, his color is too dark.
Okay now I'm shutting up.
