The forest level is made up of 4 sections.
P1 is meant to be the tutorial section, where the player learns how to jump (1) and pick up items (2).
P2 tests what the player has learned by having them jump and water again.
P3 gets more difficult, as the player has a tighter window to water the mushroom, as the water source is farther away (5). The player then has to water the dead tree blocking the river. Due to the way being clear, the statue in the water (7) is reanimated, introducing the idea that water will reanimate statues.
P4 tests the player by having them reanimate another statue (9). Because the statue is close to a rock wall, it will be able to clear the path to the end.
