Rainbow Tower

Rainbow Tower is a device made possible by Henzo thanks to the taxes gained by Whetton. It took 50 years to build. It's an enormous tunnel device with the sole purpose to link Ruluka with the Rainbow Mist. With it, Whetton hopes to take all the tresures in Ape's Concert. But when Luffy arrives to stop him, he decides to destroy Rainbow Tower by making it explode, leaving behind his family, the Straw Hat Pirates and the Pumpkin Pirates into the Rainbow Mist.
