You entered a big containment cell, it is snowing all over. There is a snowy biome on the left and a big lake on the right. Something roars in the lake and it sounds big! Then, a 1500 meter in length creature comes out of the water, it's reptile head is a skull and the rest of it's body is all thick brown skin. It does not have arms nor legs. It looks like a Skull Crawlar with no arms. This is Experiment 1936, The Skull Swimmer.
