An accurate representation of how this fight would go:
Snoke lay on his back, his face contorted in fear. Abeloth straddled him in a horrible parody of lovers, her tentacle fingers pressed to his face, her huge, grinning mouth a centimeter from his. One of Abeloth’s tentacles slithered up Snoke’s chest. His eyes widened, and his head drew back involuntarily. Snoke's jaw fell open in a wordless scream. The tentacles shot down his throat, into his ears and nostrils, and began to pulse. Horrible gagging noises erupted from his mouth. His entire body went limp and hung, convulsing, by the ropy tendrils that had been inserted into his head. Finally, Snoke's expression went blank. His complexion grew so pale and translucent that Kylo could see the tentacles throbbing inside his face, pumping something dark and viscous into his sinuses and his ears and down into his trachea.
