I haven't seen any beta online for this cave/tunnel, so I thought I'd post it here since it's accessible via the Goblin's Lair canyoneering route (or via the hiking trail).
The full beta and trip report are posted on my website here: https://dyeclan.com/outdooractivities/caving/?id=698
We did the Goblin's Lair canyoneering route over fall break after doing Ding and Dang with 8 adults, 9 kids, and pools as deep as our armpits (that was exciting!), which is why we settled on the very dry and beginner friendly Goblin's Lair route the next day.
The entrance to Goblin's Squeeze is located inside Goblin's Lair. When you're standing inside the lair looking out towards the exit, the entrance to Goblin's Squeeze will be on your right, near the bottom of the debris pile. If you follow the path water would take in a flood, this will lead you directly through the cave.

Goblin's Squeeze is about 150 feet long. It requires many, many sections of belly crawling and is extremely tight in many locations. For all but one squeeze, you can stay at ground level though.
The exit is located at the base of the debris pile on the outside toe of the slope, right next to the approach trail.

My sister Ondy discovered the cave while she was waiting for the rest of us to finish rappelling down into Goblin's Lair. She went in for quite a ways, to the first point where it gets really narrow and you have to belly crawl through the mud, and then she came back out to get others to join her. I was the next to join in, then Miller followed by Marci, Tara, and Anthony. Ondy led the exploration, which was very slow going because of all the tight squeezes.
The nice thing about Goblin's Squeeze, though, is that between every squeeze section, there is a room big enough to turn around in. About half-way through the cave, Ondy had me go first. As we slowly made our way through, we kept shouting back to the others behind us, in excitement, that it kept going! We were amazed that the cave didn't just dead-end or get so small we couldn't proceed. At one point, it got too small to continue at ground level, so we had to take the upper path over a rock before returning back down to the ground passage. Near the end, there was a drop that was about 3' tall. I didn't want to go head first down the passage until there was someone behind me that could pull me back out by my feet if I got stuck. Turns out it was no big deal because that spot opened up considerably. Anthony and Miller turned around after completing about 2/3 of the tunnel. They only had one cell phone light between them, so that made for an adventure all by itself.
Near the end of Goblin's Squeeze, I had to move several medium-sized rocks and scrape away some dirt and small rocks in order to fit through a tight passage. This makes me believe that either another group had explored the entire tunnel before, but there had been some rock falls after that group, or that we were the first group to completely explore the tunnel all the way from the entrance to the exit. Shortly after the drop, I could see daylight through some small passages that led to the surface. We probably could have climbed up to the surface at this point, but we chose to stay down at ground level. After a few more squeezes, we popped out the exit. It felt so cool to have explored this small cave and make it all the way through, especially knowing that we might have been the first people to complete the whole tunnel.
