"Hehe, I will make a giant pit underground and bury you all in it, and you will not even be able to react!!"
A giant serpent used earth elementals to make subtle changes in the ground located right below the boss arena where Jareth and the group were resting.

"You won't be able to live once you can't breathe and are buried under massive amounts of rubble and can't even cast magic… hehehehe…"
"I will bury you all alive, and then I will eat you as snack-"
