Flying Ing Caches are a variety of containers used by the Ing,[1] specifically used to house the Sky Temple Keys. Unlike other storage units used by the Ing, Flying Ing Caches do not rely on other Ing for protection. They instead use a stealth field to render themselves invisible to potential enemies.[1]

While their stealth field prevents detection from unaided enemies, Flying Ing Caches can be seen and targeted with use of the Dark Visor. They can then be attacked, collapsing the stealth field and rendering the Flying Ing Caches vulnerable to attack. After their destruction, a Sky Temple Key can be acquired.

Flying Ing Caches can also be seen while on Aether if the Dark Visor is used in the counterpart of rooms they inhabit on Dark Aether, however only a faint outline can be detected and they cannot be attacked.

  1. 1.0 1.1 1.2 "The Flying Cache was bred and trained to be a living storage unit. It employs a limited stealth field that renders it unseen to most enemies. The fact that the creature must be killed to obtain the object it stores is of little consequence to the Ing." — Logbook "Flying Ing Cache" (Metroid Prime 2: Echoes)
