Bloop the Bogroo

Your path, whatever it may be, has led you into the streets of the Citadel: a hostile metropolis sprawling with villainous monsters. You've heard that heroic characters of all shapes and sizes have tried to extinguish whoever sits in the Citadel's throne over the years, but it hasn't yet been done. The powerful creatures here that are loyal to the Citadel's anarchy normally overwhelm every hero trying to fight their way to the top. It seemed like an impossible effort, and most of the normal civilians left in the Citadel tend to believe so. On this night, the air was cold and the sky was blanketed with clouds. The city regained its signature darkness, one that politely sheltered any predator in need of prey, and gave every foe the advantage over a hero. For whatever reason, something compelled you to come here. You walk down several blocks, hearing occasional yells or crashes from inside buildings, behind fences, or within deep dark crevices. You soon spot a small, empty alley, devoid of any bizarre or suspicious clues hinting at a sinister trap. You move in and lean against a wall, wanting to savor the atmosphere or just take a quick rest. Just as you're about to leave the alley, a strange noise interrupts the windy breeze; a gross, slippery, slimy noise that continues on for several seconds. It's coming from a tiny break in the alley's corner, where you now observe a large purple creature emerge from the tight space. It's form was amorphous as it slipped into view, but it quickly shifted into a more comprehensible shape: a blobby kangaroo, with a tail the size of a tree trunk. Without a doubt, you knew it was a monster. "Hmm~ Out a little late now, aren't you?" Bloop spoke to you, his voice slick with boisterous mischief and intrigue. He let out a good chuckle and then gave you a smug glare, one suggestive enough to fluster anyone who gazed upon it. His tail idly wobbled at his side, happily smiling at you like a house pet... though its toothless maw appeared to reveal a deep tunnel of bright purple flesh. His body was certainly unusual to see, especially when compared to most other monsters of the Citadel.
