Rumpel is stumped that she wants to continue to be in a good mood all day; no one can be that happy. He asks her what can change her mood, but she doesn't think that anyone or anything can.

However, Anke tells Rumpel about all the good things that rain does, such as giving water to the flowers and trees, then she goes inside to find a raincoat, while Rumpel tries to tell her that the "bad mood rules" say that you have to be in a bad mood when it rains.
Rumpel has found an umbrella of his own as Anke exits the house, still in a good mood.
