Out in the open
What a terrible catastrophe! It is not going to be a pleasant experience. The only way to know for sure is to inquire with his fellow partygoers as to whether or not they pulled a funny joke on him by forcing him to affix himself to their tree against his will in order to demonstrate their own free will.
Regardless of whether or not this is a joke, he appears to be absolutely enjoying himself! Getting him all the way to the top and maintaining him there is a significant accomplishment, regardless of the strategy that was used to get him there. We have no choice but to pray that even if a storm does arrive, he will be able to get down safely.
So at least there’s no bear attack or mosquito bites to worry about, so there’s that to look forward to. That’s what we term “responsible intoxication,” right?
