I found some more info Zaboazagiru.That attack it did on the trailer,when it swallowed the hunter,it is a pin move(That poor Popo).It can cause the snowman affect with certain attacks and I believe it also causes Waterblight and Iceblight.Also it spews/produces a strange special liquid to accumlates in the body that produces the icy armor on its body.It gets the nickname "Garbage Shark" from it being able to increase its body size to unimaginable sizes(Huh,your right Cottonmouth).
