Rayman has to move forward, avoiding rock avalanches and stone creatures. In these mountains, Rayman meets his musician friend whose guitar he helps to recover. The big boss to defeat is Mister Stone, a creature made of rock.
The Blue Mountains is the third world in the game Rayman. It consists of a mountain range that Rayman has to climb, facing chasms and abrupt slopes as he makes progress towards the highest peaks. The meteorological conditions are significantly hard, with frequent floods and snow tempests. Rayman must be careful not to fall from the heights of those cliffs, and he must also avoid the spiked grounds, the flying stakes and the giant prickly balls. In the Rayman Junior games, stone carvings of Rayman and Mr Stone can also be found in those inhospitable rocky labyrinths. A few giant flowers, bracket fungi growing off logs and gnarled trees show the scarcity of the vegetation up there, while the numerous lava balls seem to indicate the presence of volcanic activity. Thanks to the Musician's Super Helicopter potion, Rayman can fly temporarily through the narrow and spiky crevasses.
The enemies in the Blue Mountains include antitoons, hunters, stone men, stone dogs and stakes. The boss is Mr Stone, a giant stone man. Rayman will meet him first in Twilight Gulch during a frantic chase, and eventually fight him in Mr Stone's Peaks.
