Remobra

The Remobra are small serpentine wyverns that are no bigger than a Velociprey. Their main attacks are its tail whip and poison spit. It mainly hovers in the air, attacking from above. While in the air, they attempt to ram into you, or attack you with its tail spike. They travel in groups and mostly live in the tower, although they can migrate to other areas such as jungles, swamp and volcanoes. There is a rumor that they are merely the juvenile form of another species, but this has yet to be confirmed. In MHF2 they are not seen until you reach Level 4* Volcano Quest in the Guild, and in one quest in the Elder quests. It has also been discovered that you can see them in the 4* Iodrome quest in the guild hall, but there aren't many of them.

Remobras can prove a nuisance to the hunter, especially blademasters. A simple trick to kill a remobra is to throw a sonic bomb. The sonic bomb will knock the remobra from the sky, allowing the hunter to attack it while its down.

They can also be found in a Treasure Quest from Treshi (MHF2),(Located in the Guild Hall). Although they don't give you real materials, such as Striped skin, Or any Remobra Carves.
