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.
The Bill Cosby of dinosaurs. WC need to add a shower into the game, that way when you've been attacked by a group of these you can stand in front of the mirror, cut your hair, call yourself a dirty girl and then spend all day in the shower telling yourself it will never happen again.
