The Crushing Crystals (Escape From Planet Alcatraz)

Teenagers Zak and his alien friend, Erro, are trying to make it across the Plateau of Leng before the rising sun reveals them to the robot guards of Planet Alcatraz, but suddenly mountain-sized crystals start rising through the desert sands, threatening to trap them in a circle with a giant scorpion--and the boys must figure out how to escape this series of hazards.
