ok headcanon

bear with me here

ok so you know how now we’re like OK TROLLS HAVE BOOBS

but obviously since trolls don’t breastfeed or raise their young at all, they don’t use them for the same purposes

when meenah talked to meulin, meulin started squealing, and meenah told meulin to “clam those rumble spheres” 

later on, in tags, meenah tells her to unclam those tatas

so right now we know that boobs = rumble spheres

rumble spheres. what if female trolls use their troll boobs to purr and while meulin was screaming her boobs were purring

ok that was an interesting sentence. boobs purring

but there we go. trolls can purr. or at least the females can. who knows. maybe male trolls purr too but their rumble spheres are small
