New type of currupttron

It is a curruptron that rolls quite fast in a sphere like form and can do big damage to your walls, it basically rolls straight into your walls making holes and crack, they do have little health but they’re so fast that your archers struggle. When destroying your walls they attack them, then roll back to a point to start the next attack and that’s when your archers fire coz the rolling thing (as you call it) has stopped to turn around and attack. so a new enemy for breaching walls. I kinda just came up with it in like 5 secs sooooooooo, it was just an idea
