Yes it looks terrible. I'm merely trying to present a concept, nothing too detailed or serious. I drew it in paint. ??? is just a placeholder, though in execution it could certainly work, I find it funny.Diet: Meat
Favorite Food: Painted Chicken(I'm just using this as a placeholder, honestly. Whatever chicken you'd consider very difficult to find. Dark and edgy, if possible.)
Slimeology: A lot of people like to consider the ??? slime as something evil, to be avoided, simply due to the sheer level of tenacity it takes to be able to care for even one of these slimes. However, it's just incredibly grumpy. Who wouldn't be, not being able to enjoy the sunshine? ??? slimes have a tendency to do everything they can do avoid sunlight. Caves, though, also bother them. They require very specific conditions in order to live happily, of which naturally, those conditions simply don't exist. As a result these slimes can be almost impossible to capture. Water does not calm them down, neither does feeding them, and unless pacified they cannot be captured. The only people who have ever captured them have offered their vague quotes about a situation being quite heated, but we still have no idea what they're talking about.(This would relate to a need to be near fire)
Rancher Risks: There pretty much isn't anything as dangerous. ??? slimes are far from benevolent, and will even attack(But not kill unless agitated) other slimes. When placed near other slimes, those slimes become agitated, and will do anything they can to get far away from this slime, even jump extra high to try getting out of their corrals. Due to this problem, it is considered wise to keep this slime isolated from other kinds.
??? slimes cannot become largos. Eating another slimes plort will have no effect on them due to their... shadowy nature. The worst thing you could do is let this slime become even slightly hungry. This slime is not to be found wanting. It will be able to break out of its corral(Sometimes even breaking its corral completely, but this is only conveyed rumors...) and from there, disaster falls. It starts with red sparks falling from its wings... while in this stage, which can last several minutes, it can still be fed and your time caring for it saved. However, if you aren't paying attention or you're off somewhere else, you may come back to find a very violent monster. This slime does not care for being out in the sun. It does not care for not being well fed. And if it is any of these things, it will deal heavy damage to you, far more than that of normal slimes. We believe that without health upgrades, this slime will knock you out in one stroke. It gains a speed similar to that of a golden slime, and if allowed near your other slimes, it will kill them. Suffice to say, be careful, pay attention, and don't make it mad.
A common problem also found with the ??? slime is solar shields. Yes, they work well, however it seems that this slime is capable of easily escaping its pen unless it has a proper cover over the top. It has wings, afterall... did you think it wouldn't use them?
??? slimes are also prone to mood swings. Sometimes, under random circumstances, they become irate and will lash out no matter what you do. Again, those supposed "Experienced" people say the situation gets quite heated. Am I missing on some kind of joke here?!
*As this is just a concept, I understand this might seem a bit overpowered and difficult. However, I would appreciate a very difficult to raise slime with great potential and possible rewards. Something hard to find, and even when you find it, you might not have wanted to.... A lot of people just feed carnivores herbivore plorts, and problem solved. Or, if they don't like the sun, they put them in the cave. Why not make the solar shield have a purpose? Mayhaps this particular slime doesn't like pure darkness nor pure light... shade sounds nice though. But only the perfect shade would do...Plortonomics: ??? plorts are valued for their beauty and gorgeous deep purple shine. Why, it's like looking at the deepest darkness in ones soul... Which is why they are so valued for jewelry. I suppose it really can be said rich people are willing to do anything to get the prettiest things.(In-game the value of these plorts would be near or equal to gold plorts, to reward the player for dealing with such a difficult slime)
I could hope at least this may hold for future inspiration for possible slimes in the future. Some slimes, in the end, should be valuable in inexplicable ways, and while there are other ways of obtaining such money, this road would be quicker... albeit far, far more deadly.
