Cryptids Island is the 16th Island of Poptropica, opened to general use on January 18, 2011. The quest is to recover scientific proof about cryptids - legendary creatures that may or may not exist.----------------------------------------------------------There are no "cheats" as such on Poptropica, but there are solutions at the related question below. There are also special items in Poptropica at the related question.
You can't, because it never appears. You do find Bigfoot at the end of the quest. All you can do at the Himalayas is get the lantern from the monastery and a photo of a footprint high up on the mountain. This is not enough proof. When you prove the other three cryptids, Mews will send you after Bigfoot instead.
There is no vent room on Cryptids Island. There are vents on 24 Carrot Island.
