This can be tricky. You need to get a perfect abduction on every level. To get a perfect abduction, you must abduct every sheep. You can take your time as you do not need to get them with a gold score.
- Use the antenna if you can't find a sheep. It always point to the nearest one.
- Rip up any obstacles in your way when heading to the sheep, this will speed up the process.
- Don't rush, you can press the button after completing the quota, but you will not have a perfect abduction, so wait until you get that star before hitting
- You must also do this on Multiplayer, which is local co-op. It can be done with an idle second controller, but I recommended getting a real partner as some are rather tough.
