Forest Tunnels is the second level in The Keys of Krodacia. Similiar to the first level, the exit is on the other side of the screen, but not as easy to reach. This time it is required for the player to go into the underground tunnels to find the path to the exit. There are more creatures in your path to stand in the way. The creatures you will encounter are the Hopper, Green Bird, and the Nosdrill. Completing this level opens access to Mansion, Complex, Mushroom Forest, The Underground, Forest Skies, and Slime Temple.
There are a total of 30,800 points in here. That includes 23 Krodacian Sodas, 10 Blue Peppermints, 9 Chocolate Bars and 9 Sugar Cubes, 4 Burgers and 1 Strawberry Jello (2,300 + 2,000 + 4,500 + 9,000 + 8,000 + 5,000 = 30,800). There are 42 gems to be collected, with no 1-UPs.
