(New Ranged mob) Scorpions as the arthropod counterpart of skeletons

Found in the Jungles for balancing (players could hide from projectiles behind abundant trees), dropping stings (or darts), that is used in blowguns (new fast shooting but weak ranged weapon).

Shooting stings from afar, they could spawn naturally with a random negative effect that themselves are immune, but ends up on their stings attack.

Suggestions of the negative effects could be slowness, weakness and poison (the most dangerous one).

Edit: If is not clear, this mob should be as big as a spider. Also, they could be placed anywhere, or be a entirely new thing, the point is to add a ranged arthropod mob. The scorpion just feels the best as they could have a tail animation when shooting. Their claws could be thin, so they wont be able to hold the player... The random effect could even be the same as the spiders, or none at all. Also, they could just drop flint (or any new item that seems logical) if that side idea - the blowgun - is not fit for the game.
