How to skip the Yeti Subworld without the use of tools such as a cape.
Wet Fur Skip
There is a hidden mechanic that lets you skip the Yeti Subworld every time without fail.
To do this, look at from which direction the opening to the Yeti cave is. In this case it is from the left.
Now notice there is always a 1 or 2 wide platform beneath the cave. You must hang off the side of the platform in which the cave opens up.
In this case, the cave opens from the left so I will hang off the left side. If it opened from the right I would hang off the right side.
Then simply fall straight down and you will always grab a ledge. As so.
Hope this helps!
