The Storage Cavern is an underground cavern that can be found by climbing down the well in Early Poptropica. It is filled with multiple storage crates, some of which can be moved by the Poptropican to access different areas. There are many platforms, some of which tilt, that allow the Poptropican to navigate the area to find the glow stick.
At the bottom of the room there is a stream running across the floor carrying storage crates into a large pipe. On one of the many platforms above it, a Poptropican wearing a swim suit holding a separate glow stick is standing. He tells you where to find the glow stick on the left.
The Storage Cavern must be visited to find a glow stick to navigate the Dark Room. The Poptropican must jump on certain platforms to reach the glow stick on the upper left. Certain storage crates can also be moved to help the climbing.
