The tallest of the quadrupedal colossi, its ribs are clearly exposed to the air, its legs and movement resemble those of a crab, and its eyes are notably large. It's also one of the more intelligent colossi, attempting to bait you into leaving your hiding place through a series of tricks. It gives the impression that Pelagia's head is missing from the bottom jaw up.
Some sort of weird gorilla-hippopotamus cross, it appears to have giant, fully-formed teeth growing out of the top of its head (which you hit to make it change direction) and no visible eyes-just glowing tusks where they should be.
Pelagia is perhaps the most disturbing colossus in design.
