In the 2004 Studio Ghibli anime classic Howl’s Moving Castle by Hayao Miyazaki, a girl turned into an old woman found herself in a magical castle that can move. The castle was enchanted by a wizard named Howl, and looked like four looming towers, “bespelled” to hold together around an instant bulgogi udon bowl.
YouTuber Studson Studio (also at @studsonstudio) decided to make a replica of Howl's Moving Castle. Using empty bottles and other trash and junk items, even an actual instant bulgogi udon bowl, he replicated what the castle would look like in real life if it were the size of a medium-sized dog.
If you want to try it on your own, he posted a 52-minute video on his channel detailing every step in making the replica. Be sure to also use junk items for your project so Mother Earth would be happy!
