Enemy Zombunny is working normally.
Zombear and Hellephant were not in my prefab (not sure why they were not imported with the project) I copied them from the completed prefabs and added enemyAC script to both, I also changed the animations for the hellephant as seen in tutorial.
For some reason both the Zombear and Hellephant spawn and then are stuck in place, not taking damage, and not moving/attacking.
