The kokoro, Yoruban for ‘virus’, is a concept for a fantasy creature in minecraft. The virus is a mob that mainly roams on the surface during night, retreating to shade in day, they do not burn, but they prioritize finding darkness against anything else. The model of this creature is 1 block high and 2-4 blocks long, and 1 block wide, as it resembles a centipede. Therefore the bane of arthropods works on this mob. When attacking this mob runs 1.5 times speed of the player, so you cannot outrun it. When hit by it, it does 2 hearts in easy, 2 1/2 hearts in medium, 3 in hard with no armor. This mob also bites through armor, dealing 2x durability loss. When hit, the olugbe gives 5 seconds of nausea, with a max stack of 20 seconds. Its movement is in a form such as the game centipede, one body part for each block. The death message is “player was bittened by an olugbe”. The counter for this mob is it hates bright lights, so it will not go in blocks with a light level above 10. Running to darkness immediately, pathfinding the closest exit. This is a very raw concept for a mob but I think it could be interesting to have more insects, and different shaped mobs.
