Toot had lost his patients with this place. It was obvious that a greater power than himself did not want him to explore any further.
So Toot summons an earth elemental [2nd level spell] and asks it to point out the easiest and most direct route to the surface. [7 rounds] They weren't too far from the where they entered the tunnel so Toot didn't think it would take too long. Or if for some reason it can't get to the surface, it's to at least get them as close as possible with the end point located in Soil and not stone.
Then when it returns, Toot uses his Rod of Extend to summon a Thoqqua [3rd level spell; 14 rounds] and asks it to create a tunnel in the direction the Earth Elemental indicated that is at least wide enough for Boo to squeeze through. If it can make it Boo's size than that's even better. Toot tells it to start on the side of their current tunnel so Boo has no trouble getting into the new tunnel the Thoqqua builds.
Then if all goes well, they will wait until it's cool enough and begin the slow climb [Taking 10] up the shaft. [I think you said they can move up to half their speed with two move actions? Both have a move of 40' so that would be 10' per move action. At least I think...]
