Halo 3, Halo: Reach, and Halo 4 Forge object.
It is, essentially, a hole with a flag in it surrounded by a small green hill. If a golf ball touches the green part, it rolls up and into the hole.
- When a golf ball comes on to the green it automatically rolls in if you don't interfere with it.
- The flag on the Tin Cup has a grunt head and the letters PGGA (Professional Grunt Golfing Association).
