Alien Arch Caches

These chambers contain Alien Arches and are scattered throughout the world, located in the Northwestern Mushroom Forest, the Crag Field, the Ghost Forest, the Floating Island, the Mountain Island, and the Bulb Zone. Each of these Alien Arch Caches is linked to the Primary Containment Facility, for the purpose of getting the ingredients for Hatching Enzymes, with the exception of the Floating Island and Mountain Island Arch Caches, which are connected to each other.

Alien Arches are one-way, and can only be activated by inserting an Ion Cube at the Principal Arch in the Primary Containment Facility or the Mountain Island Arch Cache. When a Principal Arch in the central hub is activated, the corresponding Auxiliary Arch activates and remains on, allowing teleportation in either direction.

Bulb Zone

This Alien Cache is found in a drop off beside the border with the Crash Zone in the Bulb Zone. It features many stalagmites and stalagtites within.
