turniplings are iconic and adorable and one of the very first things you encounter onsite! personally i would absolutely buy a runty turnipling plush.

i would bet the majority of your playerbase has no idea what a celestial pup even is... i've been playing since 2021 and i legitimately had to look it up. it'd be weird to make one for a pet that's literally been completely inaccessible for the vast majority of players for several years :P

bearnard is also iconic and probably very easy to manufacture but he's literally just a bear. if someone really wanted a bearnard plush they could almost certainly recreate him basically exactly with a generic teddy bear and preexisting build-a-bear or doll clothes. I think if a plushie was made of any NPC it should be someone with a more distinctive design! if we're going for louise hill npcs my vote would be for calbet or buli first... or fantasia and lilia specifically if both of them were made at the same time.
