It’s literally the power of friendship to the rescue, which is cheesy as hell even for One Piece standard, i can’t (and won’t) make this shit up. Law reveals why he “betrayed” them, and eventually they join forces, and thanks to the Tongari Island’s Den Den Mushi (who apparently runs on “friendship powah” energy), they get a power boost so big they actually manage to beat Kizaru. But after merrily eating at the food stands, checking out the shops and enjoying a bit of roulette, they reach the cave Law told them about, and they’re ambushed by the Marines, complete with Sentomaru, Fujitora, Sengoku and Kizaru. The premise is that Tokyo Tower exists in the One Piece universe as an island, Tongari Island, and the Straw Hats reach it after being told of a secret treasure by Trafalgar Law.
Sure, it’s not ideal, since the short was supposed to be seen in location on a panoramic multi-screen fashion (with some lights used to enhance the experience, like for Kizaru’s attacks), but it’s still better than it being lost media. This specific featurette not only was shown exclusively there, but only for the “Luffy’s Endless Adventure” Exhibit in 2018, so it’s just thanks to whoever filmed this with their phone (or hidden camera) that we can actually see this featurette in any form. If having to go at selected water parks and such places to see the 3D featurette Trap Coaster seemed asking a lot, don’t worry, this time you – only – had to go to One Piece Tokyo Tower, the only One Piece theme park in the world, situated inside Tokyo Tower (in case the name wasn’t clear enough), open since 2015… and closed – permantly, to boot – this 31 th of July 2020.
