This...is not a very nice space to have to crawl through. The rock-hewn portion scrapes uncomfortably at times. It's only because of his soft shell that he's able to squeeze in at all; any of his other brothers would've had a hard time, pun intended. Raph wouldn't have gotten in past his head.

Donnie's just glad he's not claustrophobic, although he wonders if the poor soul that had been stuck with this job ended up with such. Being in such close quarters does afford him a good look at the handiwork. ...he sure hopes no one died carving these things out, ugh ugh ugh why did he have to think about that just keep going just keep going...
