Erupe (エルペ) is one of the two small monsters first identified in MHFO Season 9. It appears in a new area called the Highland. It has a very similar move set to the Kelbi and the Anteka. It's a very friendly creature and especially curious towards hunters.
Burukku (ブルック), is a Bison shaped Herbivore that is exclusive to Monster Hunter Frontier and is one of the first small monsters, besides Erupe, to appear in the game. It first appeared in Season 9 and inhabits a new area called the Highland. This herbivore is likely a favorite prey to the Gurenzeburu.
The Highland (高地), also known as the "Fields of Natural Calamity" (天変のフィールド), is a new area in the upcoming Monster Hunter Frontier's Season 9 update. As the name suggests, it is an area of high rocky plateaus.
The mountains and towering cliffs are largely unexplored. At the summit, there is a deteriorating forest with weathered rocks - below is an endless sea of clouds. Waterfalls are plentiful in the area. The deepest part of the Highland, in Area 4, is a cave characterized by huge stone pillars. The Hunter's Guild refer to this area as the "high ground" although it is still shrouded in mystery.
