8.0.4 UPDATE
Gallimimus ('gall-e-mime-us', meaning "Chicken/Rooster Mimic") are medium to large sized ornithomimid prehistoric creatures from the Late Cretaceous period in Asia. They were added in Build 6.2, are diurnal (meaning will be active during the day and sleep at night) and are the only ornithomimids in the game. They are also the only flocking animal in the game. They are approximately 3 blocks tall tall and 6 blocks long at adulthood. There is no size difference between the genders, but feathered males have a red front torso and a bright red crest, and unfeathered males have a blue face. Newborns are 0.1 blocks tall, and are fully grown in 10 ingame days. They can be given essence of chicken to grow faster, at the cost of hunger.
Gallimimus, like almost all other mobs, has a mood that can drop or be raised through various means. Having a low mood means it may attack or avoid you, having a high mood will make it passive. Right-click it with a DinoPedia to see what its mood is at.
A fossil version of the gallimimus can be created by right-clicking a bio-fossil on the ground, which will create a random skeleton of a Mesozoic-era prehistoric creature with a small chance of it being a gallimimus.
Like most other mobs in the mod, they do not spawn naturally in the world and must be created by the player through the culture vat. As they are dinosaurs, they hatch from large eggs that need to be warmed by any light source.
Real Life
Gallimimus bullatus speciemens have been found throughout the Gobi Desert of Mongolia, which would have also been a semiarid desert-like area during the Late Cretaceous, possibly similar to the Okavango Delta in Botswana.
BEHAVIOR
Gallimimus is a flocking dinosaurian creature that will stick together and defend each other when attacked. It is not very large, so they cannot break blocks. They have an advanced herding AI that means they will form individual flocks which will always stay together and defend each other. When alone, they will run from predators; however if a member of a flock is attacked, they will fight to the death, which, depending on the predator and the size of the group, can lead to entire flocks of gallimimus' being killed. They are very fast mobs however, and are opportunistic omnivores that can often steal meat from recently killed mobs. When attacked by a player, they will usually give up the chase relatively quickly as they only want the threat out of the area. They will also naturally seek out and eat plants and leaves. They also can ride in Minecarts
When on their own, they are prey to allosaurus, ceratosaurus, dilophosaurus, sarcosuchus, spinosaurus, and tyrannosaurus. Baby gallimimus' are targeted by a wider array of carnivores as well. There appears to be a bug where the predator will only attack their specific prey gallimimus and ignores the rest of the flock, even when the specific gallimimus is killed, which usually leads to the predator slowly dying.
Gallimimus will interact with scratching posts, tethered logs, and will chase toy balls, bringing up their mood significantly. They are diurnal, meaning they are active during the day and will sleep at night.
Adult gallimimus' can breed and lay eggs every five minutes as if there is a male and female present. The breeding probability is handled by how many individuals are nearby.
TAMING
Gallimimus can be tamed similarly to most other prehistoric creatures. The easiest method is to be within six blocks of a Gallimimus' egg when it hatches. Alternatively, a Gallimimus can be tamed using a whip, or by being hand-fed. They are rideable after being tamed.
RIDING
Tamed Gallimimus are rideable once they are 10 days old. When ridden, they won't go hungry and can't grow up. They can only be controlled if the player is holding a whip. The controls for movement are based on the direction in which the player is facing. Entering water that is two blocks deep or more will result in the player being automatically dismounted.
Movement while on a Gallimimus can at times be jerky. Occasionally, the animal may stop moving completely.
FEEDING
Gallimimus do not hunt other mobs when hungry, but they do eat meat. They will also seek out and eat ancient ferns, flowers, grass, and leaves. They can eat items dropped on the ground, be hand-fed, or eat from a feeder if one is in sight. Its diet consists of apples, seeds, wheat, bread, porkchops, sugar canes, eggs, sugar, cakes, cookies, melons, melon seeds, pumpkin seeds, beef, chicken, carrots, potatoes, pumpkin pies, Dillhoffia Seeds, ferns, Failuresaurus Flesh, all aquatic spawns and all prehistoric eggs.
