At the end of ep 5, the way to solve the problem was to give a depressed, floating king NOT a black, dark, held raincloud, but a compressed cloud of wretched stink. In a way, it was empowering. He didn't bring a dark cloud, just a cloud that was subjectively bad.

In fact, they had a song about that. The stink had appeared pleasant to a few folk in the show already. The fact the depressed king liked it, and so did a main char, came up. But at the end, everybody sang about how they cause no trouble to be themselves, as everybody does different harmless things.

Hmm, I can't find it here
