Spitter Spider

A new spider mob, the spitter spider. I don't think there's an actual spider that spits at prey or predators in real life, the closest thing I can think of are tarantulas shooting their hair at predators, so maybe replace the fictional spitter spider with a tarantula mob. Anyways, as the name implies this would be a spider that shoots a projectile at the player. I imagine this spider being a rarer variant to normal spiders, so they just spawn wherever normal spiders spawn. Having a projectile, maybe these spitter spiders would be slower. But the fun part is that the spitter spider's projectile has a slowing effect on the target, thus if you get hit, the spitter spider will make its way to you and bite you harder than normal spiders, or just give other mobs a chance to attack you. I think spiders are a rather forgotten mob, so having a new spider to revitalize that subtype of enemy would do them some good.
