The Forest is filled with bug enemies, mostly Bees and Dragonflies. There is not much water, as there is plenty of solid ground. About three quarters into the level, there is a Bonus Stage Gameboy. Halfway through, there is also a Heart which can only be accessed by dropping your Balloons, and it is guarded by Crocodiles which will instantly kill you, similar to the Walruses in Ice. There are some ceiling spikes right before the boss fight, though they are small and easy to avoid. During the boss fight, you are given two small platforms on both sides of the Boss, who is on a lower larger platform.
