Hello peanut this is about your question on the abby skin mod.

abigail changes body shape based on what wendy head you are wearing.
this whole mod is based on using the default abigail flower skin
if you use the alternate abigail's flower skins it will replace the flower on abigails head.

You will see the flower on her head gets replaced By the skinned version of the flower you use.
this affects mainly (rosete, lureplant,survivor,creepy, )

all of the other wendy skin heads have their flowers stay on the model and the new skinned flower head just layers on top of the existing flower making it look ugly.

but i couldn't do anything about those because they already have dynamic flowers adding visuals like
scarfs,Blush, or even changing abigails form completely (magmatic)
