In the Steam survival sandbox game ARK: Survival Evolved, there are some creatures that are masters of using chemical agents, and they are like fart worms, releasing chemical factors in the body when they encounter danger, so as to achieve the purpose of escape. The ARK: Survival Evolved is one such creature, it can release two different chemical gases, the purpose of using these two gases is the same, that is, to make the Pachycephalus better survive in the dangerous ARK: Survival Evolution world.
The size of the Pachynos is somewhat similar to that of the Triceratops in Ark: Survival Evolution, but unlike the Triceratops, the Triceratops did not take three sharp horns that were enough to slaughter the Tyrannosaurus Rex, so it had to think of a better way to survive in the world of Ark: Survival Evolution, so the Pachynos evolved a huge nose, and when the Pachynos were in danger, it could release chemical gases through its nose to escape disasters on its body.
When the Pachycephalus needs to pass through the territory of some dangerous creatures, it will release purple gas, which can make the Pachycephalus have a covert effect, even if the Tyrannosaurus Rex and the Southern Giant Beast Dragon will calm down after inhaling these gases and no longer attack the Pachycephalus, but this gas is ineffective for some higher creatures in ARK: Survival Evolution, such as humans will still beat it violently after inhaling this gas.
When confronted with these useless creatures of purple gas, the Thick-nosed Dragon in Ark: Survival Evolution will release a red gas, which can make the creatures around the Thick-nosed Dragon become angry and attack the creature that attacks it, but it is ineffective against creatures such as Tyrannosaurus Rex and Nanju. Therefore, before taming the Thick-nosed Dragon, the player must ensure that there are no medium-sized dangerous creatures around it, otherwise the player will not be killed by the Thick-nosed Dragon in the end, but by the "helpers" it calls.
