It will occasionally roll in dirt and mud, possibly to cool off from the hot desert sun.
When it awakens from its subterranean slumber it will shake off all of the excess mud and dirt that gathers on its back; if a hunter is close enough to it, the excess earth that flies off will become attached to the hunter and quickly dry due to the desert heat, inflicting the new status effect "Muddy". Muddy is just like the Snowman status, although its slightly easier to get free from. It impedes the Hunter's movements, slowing them down as if they were carrying a heavy object (like an egg). While the Hunter can still roll, they are also unable to use items for a short period of time (except Cleansers).
When hit by mud, hunters also experience Waterblight, which make stamina recover slower, but stamina is not lost by sprinting while you are suffering from the muddy status. After the Barroth has shaken off most of its mud, it will roll around in muddy water to collect more.
Although docile when undisturbed, Barroths become extremely territorial when a creature interrupts its sleep. It will release an initial warning roar. If that fails, it will continuously attack until the threat is exterminated.
Barroth is perfectly adapted to life in the Sandy Plains. They cool down in mudpools at the hottest parts of the day and feed on Altaroths. Its nostrils are located on the top of its head, which allows it to almost completely submerge itself in mud for prolonged periods of time without the danger of suffocating.
The Guild Sweetheart says that a blunt weapon, such as a Hammer, must be used to break off Barroth's head ridge. It's not required to use a Hammer in order to do so, but due to the fact that the head crest is hard bone, it's much easier with a Hammer. Hammers are the only weapons capable of not bouncing off Barroth's head if under blue sharpness (unless the Mind's Eye skill is activated, or the Hunter is using the Spirit Slash on a long sword). She may just be hinting to the player of this mechanic.
