Royal Highlands

Royal Highlands is one of the midgame caves in the Awakening Arctic in Pikmin 2: New Year. The cave is an ancient castle ran by an elite society of organized Grub-Dogs. The cave is extremely difficult due to the massive amount of different Bulborbs and other massive enemies residing within the area. Despite this, there are a lot of valuable treasures in the cave, mainly being gem and ring themed. The total price of treasures in the cave is, with the Brute Knuckles being the main treasure.

How to reach
"I'm detecting countless numbers of creatures ahead, as if they're having a meeting of some sort. The interior within appears to have aged for a very long time. Ancient history, this is."

- The Ship, upon discovering Royal Highlands There are a few obstacles blocking you from the Royal Highlands. After killing the Violet Dirigibug and Toady Bloyster, you can tear down the poison bramble gate. Use the seesaw to get to the top and get the Yellow Pikmin to tear down the electric gate to get to the area. If you have Blue Pikmin, you can tear down the flooded bramble gate and clog near your ship to get to the area quicker. There is a group of Snow Bulborbs and a Hairy Bulborb next to the area, so be wary.
