Here is my entry for the #monstercrowndesigncontest Its inspirations come from the Pipa Pipa Toad, Hairy Frogs, and various birds like Macaws. More info in the replies:

This guy was going to be my plan B if I didn't have anything for the contest. He was originally going to be a mod. I Wanna be clear this is not me making another submission for the contest. I kinda just wanted to give this guy some spotlight because I'm also very proud of how this guy came out.

#monstercrowndesigncontest My entry is Optigris, the Wicked Watcher! Optigris‘ eyes can unleash devastating dark energy and can see through physical objects to spot prey. However, these eyes are a double edged sword that are also its weak spots. Optigris has stripes in an attempt to hide them.

My entry for the #monstercrowndesigncontest is Phasmoetia, the Bleeding Stake. Based off of Phasmids, Plasma, Wooden Stakes, and Blood Magic.

"Abyss's Venom, Cuttlprinus" This creature is inspired by jellyfish, cuttlefish, and inkcap fungi. It's for #monstercrowndesigncontest. It inhabits abyssal waters, unless shallow waters are polluted, and if it touches you, you will definitely wish you were dead, either because of the pain or venom.

My Entry for the #monstercrowndesigncontest is The Luminescent Torrent, Gorelacus! You can read about its design elements and lore on the image itself, but I've put the main journal-esque entry lore piece and the top left info in the Alt Text for those who need it :)

#monstercrowndesigncontest Since the contest asks for an Unstable Demon, I came up with this: something like a Fallen Ophanim, with tentacles instead of wheels and suckers instead of eyes. I can't draw but you get the idea.

My submission for the #monstercrowndesigncontest, Silclio! This mysterious monster floats aimlessly at sea, motionless until something comes within range of its tentacles. Contact with those tentacles induces a catatonic stupor, with the worst victims entering a coma from which they never wake.

my entry for the #monstercrowndesigncontest YAAAAY since it's an unstable devil, i imagined it being physically weak but incredibly strong magically/mentally :) and struggling to lift itself up because of its huge heavy head. enjoy my creature
