This happens when you let these aberrations grow up. post #33780 If you let yourself be fooled, if you think they are just simple, gentle creatures... in short, if you let them wander around for a couple of weeks, here's what happens: post #52845 It will start with them just sitting around and doing the usual, silly things... and you won't notice that they stopped walking. Soon, as you can see in the second picture, their former legs further solidify, becoming BALLS, thus giving them huge doses of testosterone and amplifying their natural aggressivity.
"Yu, yu" they say, "Mister Human, yufufufu..." they laugh, pretending to joke as usual while you think they are just chatting. False. Soon, new legs grow up to compensate for the previously lost ones, but since testosterone's level is now quite high they are now hairy and stinky. Malevolent.
Well we could argue that they were already malevolent without a single trace of testosterone, kinda why they are at odds with everything else in the world...
