Someone post the "3 mikes each symbolize a skeleton" image I think it's one of the best theories by far.

Jongler=Papyrus
Battat=Sans
Pluey = Gaster
the last one has:
>pink and yellow eyes
>darkness associations
>roaring/shelter connection because of the Pluey minigame about the flood
>"the mike that listens"
>has mics for fucking hands aka SPEAKS IN HANDS
