Don’t make my mistake and think they’re fluffy and kind of cute and decide to approach them without checking if they can eat your face off first.
They are the Ark equivelent of the Killer Rabbit of Caerbannog. And they are hungry for your emotional trauma.
Probably the most vile, evil, and sadistic being in ark. This ferocious little lizard will put you to sleep with its magic jump-and-toe-jab-venom. Once you are asleep, most Troodon will just dance around your unconscious body until you wake back up, only to knock you out again. These beasties are even worse when they travel in packs. Do yourself a favor and upgrade your armor and weapons (especially) asap. The faster you can kill them, the better.
