Skeletal Mutated Horses

These things are basically just horses who got sucked in to the flesh and stuck there for days mutating into a huge abomination. The same as what happens to the victims of the Chompers (https://sticknodes.com/members/godzillamaster1/activity/1666224/), their skin starts to disintegrate into nutrients for the ever growing flesh.
They grow two huge tongues, grow (around) 5x their size, their skeleton is a lot more visible showing that they have less fat, their eyes glow a neon red colour, they lose ALL their hair, and their tail grows a lot larger.
