Eetle

The Eetle is a neutral mini-boss mob added by The Endergetic Expansion. It is the first and original mob created for the mod Endthereal.

Spawning
Royal jelly is created by combinging portoplasm with a Eetle Wing. This can be fed to a Leetle transform it into an Eetle.

Behavior
In Endthereal, Eetles spawned wild in the Outer End islands. In The Endergetic Expansion, they may spawn near mounds in the future.

Eetle Wings / Elytron Fragment / Husk
Dropped by Eetles, their wings or Elytron Fragments can be used to repair Elytra. The ability to repair Elytra with leather has been disabled.

Previously this created the Armored Elytra which had extra armor and when broken produced an Elytra. Previously Eetles dropped husks, which could be combined with a Elytra Blueprint to craft an Elytra.

Leetle
Leetles are a smaller version of the Eetle, generally found 2-5 near a mound. They can be used to spawn an Eetle.
