Zerg baneling discussion

The structure needed to Build banelings. It is available after you have morphed a spawning pool. As with all Zerg structures, it releases a small amount of broodlings upon its death.

The baneling nest is actually a gigantic creature found on the planet char, it digests the minerals from the creep and uses those minerals to create the green material that a baneling is filled with. Though the creature can move, it's permanently bonded to the creep below it due to unknown reasons.

When the Zerg went into hiding, and evolved, one evolution they created was the Baneling. The Baneling can be morphed after this structure is complete. It contains all the DNA codes to do so and contains one upgrade for the Baneling.

Evolve Centrifugal Hooks - After this has been upgraded, It will allow to Baneling to roll, thus making it faster.
