Blue Forest is the first level in The Keys of Krodacia. Like most beginning levels it is rather easy to make it to the exit. All you do is move from one side of the screen to the other. There is an underground area accessible by two poles. Blue Forest, just like beginning levels in Keen 4 and Keen 5, has an abundance of extra lives and a secret exit hidden. Completing this level allows access to Forest Tunnels and Private Manor. The creatures you will encounter are Patsy, Nosdrill, Green Bird, and Brombo (on hard difficulty).
There are 10,100 points in this level. That means 11 Krodacian Sodas, 15 Blue Peppermints, 2 Chocolate Bars and 5 Sugar Cubes (1,100 + 3,000 + 1,000 + 5,000 = 10,100). There are no Burgers and Strawberry Jellos at all. The total number of gems is 24. Seven 1-UPs are near the secret exit.
