Just Chillin'

My first attempt at creature of the week over at conceptart

Concept: Frostshell Colossus

These giant beasts can be found deep within the largest deserts. While feared by any other creature capable of living in the same area, they are also the reason other creatures can survive. Using their gigantic claws, they dig themselves underground finding subsurface lakes. They will then proceed to fill up their shell and freeze the water, while doing this crystal-like spires are formed on its back. The Frostshell Colossus then returns to the surface, where it creates a pond by smelting the ice crystals while hiding halfway underground. When other thirsty wildlife appears to drink some of the precious water, the Frostshell Colossus strikes, often killing multiple preys at a time.
