Giant Jack

Giant Jack (巨大豆蔓 (ジャイアント･ジャック)) is a giant beanstalk in the center of Upper Yard. Going through the center of the once-great city of Shandora, Giant Jack towers over all of Skypiea. God's Shrine rests upon an island cloud that the Giant Jack goes through, but first there is still a deserted cloud where Zoro, Wiper and Ohm have their showdown. The Golden Belfry was knocked up by Giant Jack, and resides on a cloud nearby. It first appeared in Chapter 249 and Episode 163.

Giant Jack no longer stands in Upper Yard. When Monkey D. Luffy and Nami wanted to ride the Waver up to Maxim and approach Enel, Nami sent a makeshift note to everyone standing near its root, to tell them to chop down Giant Jack to the west. One stem was cut by Roronoa Zoro but it didn't move a bit, Usopp tried to attack the other to no avail, Nola hit it with her head, and Wiper used his Reject Dial to attack the other stem, attempting to completely chop it down. It made a bridge that led Luffy to Enel.
