Cryptozoology is a term that refers to the subculture and pseudoscience that attempts to explain the existence of creatures from Mythological Folklore rather than accepting the fact that it was probably just a piece of driftwood out in the lake. Some of these creatures may sound failure to you; creatures such as Big Foot, Mothman, Chupacabra, or The Loch Ness Monster. My proposal is to make a mod where some of these creatures will spawn, but have an incredibly rare spawn chance and try to keep their distance from the player to add a sense of mystery. Ideally it would be a neat feature to have it hidden away in some other mod where players are none the wiser, alluding to the mystery that was Herobrine long ago in Minecraft's heyday. Some of these mobs may be purely Atmospheric while others may act as threats.
Mobs might include the following:
Bigfoot: Spawns in Oak and Roofed Forests and tries to hide from the player by standing behind trees. When provoked he will stomp the ground and stun the player until he can get away. Bigfoot calls can be heard from a 30 block radius Yeti: Essentially the same thing as Big Foot but in Snowy Biomes. Mothman: Similar to Update Aquatic's Phantom Mob, Mothman will Swoop down at you in the middle of the night letting out a loud screech and lift you into the air then drop when it sees fit. Mothman can only spawn at Dusk, and from a certain distance away from the player; Mothman will stalk the player and gradually get closer while grounded, but will remain staring at the player with glowing red eyes until it flies up to attack. Only way to avoid Mothman is by staying out of his line of sight for 2-3 minutes. Nessie: Spawns only in the Ocean and will dive below to spawn once viewed for 2 seconds. UFO: UFOs travel in angular motions within 3D Space. They will attempt to abduct Cows, Villagers, or even Crops. Werewolf: Packs of wolves may rarely harbor 1 or 2 of a Werewolf variant. When the Moon is full The Wolves will turn into Werewolves and seek to kill the player if the player is near. Werewolves will have glowing yellow eyes so they are more visible in the night. Every night all wolves will howl at the moon to signify when night mobs start spawning (Additionally add roosters calling to signify when day starts) on nights of a full moon all wolves will howl like normal, but werewolves will have a more monstrous howl. Vampire: Bats will now naturally spawn at night, and have the rare chance to be a Vampire Bat. While in bat form, Vampires will try to stay out of your sight while attacking you from behind with small little bites; once you spot the Vampire Bat in a 5 block radius it will turn into a Vampire and try to attack you in it's Humaniod form. The only way to kill a vampire is with a wooden sword. If you swipe at it with anything other than a wooden sword it will turn back into a bat and flee. Vampire bats will seek cover much like skeletons during the day, otherwise they will burn in the sun. Ghosts: Ghosts will spawn randomly throughout the world and are invisible and become less transparent the closer you are. Ghosts will open doors, trapdoors, put out torches and fire, bang on anvils, activate noteblocks/jukeboxes, flip levers, press buttons, and open chests while using items it finds as a projectile to hit you. Ghosts will despawn as soon as day breaks. To avoid ghosts at all you will need a totem. Chupacabra: A fast creature that will stray away from the player at all costs; it's only function is to kill sheep and chickens in the night.
Flatwoods Monster: Stalks you from right behind and makes no noise while leaving path blocks where it walked, once you turn around it runs right at you and despawns once out of sight. Gnomes: Small creatures that spawn in Flower Forests, Tiga, and Mega Tiga. Gnomes will usually keep their distance hiding behind trees; if they smell valuables on you, such as items relating to Gold, Diamonds, or Emeralds, they will attempt to run up to you and pickpocket you when your not facing them. Herobrine: Herobrine returns as the same creepy anomaly he used to be; Herobrine has a a few more functions than the other Cryptids. Deep underground Herobrine will dig out long 2x2 tunnels, leave sand pyramids in the ocean, or cut the leaves off of trees, mobs near him will gain white eyes. Herobrine will occasionally teleport behind the player for a one hit kill, otherwise he stalks you from a distance; if you stare at him long enough you will begin to get nauseous and unable to move until he leaves. Occasionally while laying in a bed, Herobrine will walk to the foot of your bed and stare at you and you wont be able to sleep, he despawns as soon as you get out of bed, but if you wait your health will eventually deplete. In appearance, Herobrine will have glowing white eyes, and a crooked twitching head.
