Warworm

Warworms were giant, mutant worms bred by Asp Bloodthorne. Massive and segmented with grey flesh, Warworms were adept tunnellers and were credited with excavating tunnels under a stadium in Texas to allow Asp's forces to take ninety thousand humans as slaves. Warworms could also swim and fight in the water, as they destroyed over twelve Russian nuclear submarines in the Avacha Bay of Petropavolvsk.

Description
Warworms were gigantic creatures, capable of digging tunnels with a large enough diameter for an entire cart to move through. They had grey flesh and were segmented, but unlike regular segmented worms, Warworms had eight small black eyes and "a gaping, leech-like maw".
