Kevin vs. the Volcano (1x8)

:

When a volcano erupts, Tom assigns duties to everyone, then leaves in the truck with Christa to create a lava dam. Kevin, who resents being stuck near home with a menial task, deserts Annie, Stink and Tasha and goes off with his camcorder. While videotaping the volcano, he gets trapped in a quicksand bog.
