"From atop its sunning boulder, this small monkey peers at you with eyes full of curiosity. Two puffs of grey fur billow out from either side of its face."
Baboons (except Hulking) fall back when approached and try to throw stones. They tend to appear in packs. A lone baboon is no threat even at level 1, but several can stone you to death with surprising speed.
Hulking Baboons can carry/throw small boulders sometimes!
Shrewd Baboons are probably the most dangerous in that they can plink you to death without you quite realizing the danger until it's too late. Very shrewd indeed!
