This is an enormous oceanic crab species - far larger than a woolly mammoth - which lived during the Pleistocenic ice ages. It has a metallic blue color, long eyestalks, and its mouth is extremely large compared to its body. It made an appearance when it climbed on the ice float and attacked. But when Sid and the crab noticed the giant wave coming, Sid clings to its leg. When the wave passes Sid tries to thank it but he is horrified to see all but it's leg was washed away. It's status is unknown but it could have survived because it lives in the ocean and Arthropods regenerate lost limbs.
