Yeti

The Yeti is a cryptid in Cryptids Island.

Cryptids Island
Go to the Himalayas. Head to the top of the left mountain and find the young-looking man. Ask him to be your sherpa and he will take you up the mountain. To get up the mountain without getting blown off, you have to jump ahead of the sherpa and tie your rope to one of the rings. You can skip rings if you're fast enough. If you fall off but your sherpa is tied on, you can climb back up the rope when it stiffens.

Summit
When you reach the top of the mountain, go inside the temple and talk to the head monk. He will give you a lantern, which you must light with the matches. Go outside again and up to the roof of the main building.

Temple rooftops
The monk up there will challenge you to a board game, where you have to get the Yeti past the hunters from one side to another. To avoid being cornered, jump diagonally up and down. After winning, the monk will let you through. Jump up to the roof of the building on the right, then run up the rocky cliff until you spot a supposed Yeti footprint. Take and picture and head back to Mews. He will say that it is just a boot print and that there is no point in looking in the Himalayas anymore. After you finish this and the other missions, a new sighting of the yeti appears.
