Five little paper boats drift along a stream at the front of the night deck, each with a dark lamp on its mast. Lumen hops and a ripple runs through the water, pushing the boats along and lighting their lamps in teal. Orange and Pink take turns, and each ripple sends the boats forward and changes the lamp colours. The friends hop in pairs and then all together, and the ripples grow. At last all three hop together, the boats' lamps burst into bright stars, the stream turns to rainbow light, and the boats sail on with sparkling trails.
