I think it's the fact that Riley incorporated their skins into the bunny one. It's fine. :PWas looking for a skin to do a similar thing with my friend, found this on minecraftskins.com https://www.minecraftskins.com/skin/14043265/easter-onesie-and-slipper-boy--ce---2/
and this one from 2 YEARS ago https://www.minecraftskins.com/skin/12312262/bunny-boy/
are you sure you made those skins?
