Original Description:
 
Day 5 of 30 Days of Draconequus: Sludge! He lives in a swampy bayou like area with his three sisters! They were sent through time by his parents when he was a boy and his sisters were still in their eggs to save them from the cataclysm. He’s about the same age as Dozy now and his sisters are a about ten years younger. Discord senses strong magic from his swamp but has never thought to check it because why would he expect more draconequus to resurface? So Sludge and his sisters live unbothered for some time until they are eventually discovered by Dozy when she goes off on a little adventure to the bayou to find a rare carnivorous plant.
