Celestia watched as her sister's head was melted into a pile of sludge by the acid, leaving nothing but a raggedy stump and a greeny-red pool by the alicorn's hooves. The now headless body attempted to come towards her, staggering left and right as much as it managed forwards, before eventually slumping over, rear raised up into the air, one leg twitching randomly. Celestia couldn't stop giggling as she levitated the slush that used to be her sister's head into the bucket, wondering if the alicorn was still conscious.
