Today I visited Looney tunes which actually turned out to be bigger in reality than what it looked like in pictures. I will probably get around to posting photos of Tea Tree and Xirth soon on here as well.
1. The entrance - All 3 pipes are separate but start off at identical junction rooms.

2. Going a bit further down - I decided to take the furthest pipe to the left.

3. The first junction room - You have to jump over a little wall thing to access the rest of the pipe

4. Other side of little wall thing

5. Entrance to second pipe section

6. Looking back from the 2nd junction room (about 400m down)

There is more to it but I didn't take photos of every section of it.
