Describe in detail what happened with the cloud-men.

In Chapter Twenty-seven, Centipede taunts the Cloud-Men, even though the others try to quiet him. The effect of his yelling is immediate: the Cloud-Men launch an attack on the peach. They throw hailstones, and James instructs everyone to lie down. The hailstones whip past their heads and smash into the peach, projectiles hit Ladybug and Centipede, and James subsequently instructs everyone to dive into the tunnel to avoid further injury. When they try to light the space, they realize that Glow-worm's light has been broken. Fortunately, the noise of the hailstones ceases, and they all climb back up the tunnel. For the time being, there are no more Cloud-Men in the area.

In Chapter 28, the passengers look up at the sky and see an arch in the distance. They fear that there are Cloud-Men surrounding the arch, and they are correct! Cloud-Men are painting the arch, and upon closer inspection, James and his friends realize that these Cloud-Men are creating a rainbow. The rainbow is supported by a series of ropes, and the Cloud-Men are preparing to lower it down onto earth.
