Ever seen an angry Gallimimus?
Try snatching an egg out in the wild.
Try not to laugh.
Laugh,coz they'll run after hitting you once or twice.

These guys are harmless and seem to hang around the swamps or near the edges of the redwood biome.
They die faster than parasaurs, but will escape much easier. Swift attacks from a carnivore or a strong headshot will take them down before they run.

When encountering one of these, stop immediately in your tracks and grab the closest music device and start playing "Running in the 90's" Then proceed to chase and kill the creature.

Very abundant in the grassland by the green obelisk in ragnarok.
