Hey guys, Duder here.
I just wanted to show everyone how to climb up the walls of the new Clothing Store in the Town area. The staff will likely fix this glitch in the near future, so try it out while you can. It's pretty cool! (You get a whole new perspective of the island that high up haha).
Here's a short video that demonstrates how to climb up and across the building. Enjoy!
