Cheating the Cycle of Life- A Padded Pony Collab

Scootaloo seriously wanted to cry in panic and anguish, due to the itchy sensation she felt all over her coat, and the terrifying sensation of total immobility.

Except she could not do that.

"A little more plaster there..." Twilight said, as she levitated a ball of fresh building material, and smeared it around Scootaloo's only uncovered parts, her butthole and flank.

"Why Twilight, why?" Scootaloo cried out, as Twilight Sparkle smeared the plaster onto Scootaloo's flank. Twilight Sparkle shrugged, as Scootaloo's tiny blank flank disappeared under a layer the greyish white cold malleable substance.
