If you put your mouth on a tree and try to eat it, you’re probably a distressed and troubled individual (unless you’re a woodchuck). You don’t need to eat this tree, you have plenty of food at home. Get your mouth off that tree you distressed child.
You thought you were the most distressed and troubled person in this situation, but then you look up and see a very equally distressed and troubled condor (こん). The tree you've been mouthing is its home. And now you've slobbered all over it, ruining this condor's day.
