This is the first island in the game. The levels are set in meadows and mountains and are easy to master. However, you will have to pay attention to the lava rivers coming from the volcano. Displaced for the various levels there are then some wells that give access to underground caves that you will have to explore to recover all the diamonds and free all the Gobbos.
