A big wooden metronome stands at the right of the night deck, and its arm starts to swing with a tick, tick, tick. Lumen hops on every tick, then Orange and Pink join in turn. The weight slides down, the ticks get faster, and all three friends hop together in a quick little rhythm. Then the beat slows, and on the very last tick all three friends jump and three big music notes fly out of the metronome and float above the friends.
