Lucky Beast suggests that Serval and Kaban take the line cart up to the mountain so they can charge the Japari Bus' battery. But the cart is missing when they arrive. As they try to find a different way to climb the mountain, Japanese Crested Ibis flies down and greet them with her song. Kaban is impressed by Ibis' song and how pretty she looked. Serval, on the other hand, found herself rather dizzy from Ibis' tonedeafness.
