This chorus was actually mostly stills; I think that my energy for animating intricate frames was running out, so I didn't want to make this final verse too complicated.
One thing I did do, however, is that in the first frames when Klause wakes up from their dream, I made a smear frame to indicate urgency. This is a technique that was commonly used in older cartoons, so it is a bit of a pastiche of older animation styles.
