"What in the name of biology is that?!"―Indiana Jones[src]
The Ice Creatures were inorganic, energy-based beings that patrolled and violently protected the various hallways of Shambala Sanctuary, presumably for thousands of years. They stood on two legs and moved around either by rolling or by simply running. Though they appeared to be reptilian, they had translucent bodies seemingly made completely of ice. Most of them were small, however a colossal version, known as the Ice Guardian, was also created to protect the inner sanctum and Urgon's own personal study.
The ice minions, believed to have been crafted by Urgon himself, were likely responsible for killing the monks and attacked any intruder by spitting stinging icicles. They usually could be taken out quickly by gunshot, disintegrating into icy shards.
