This is pretty much a curved path to a hole to the next sublevel. Scattered Dwarf Red Bulborbs are everywhere, and the Energy Unit is by the pod. The Foilage Creation Container is in a Dwarf Red Bulborb.
This is just a short path that's still curved. A Red Bulborb rests in an arena, and is the boss so to speak. Defeat it for the Water Containing Device. Then take the Geyser back up.
