Now that this chapter was adapted, a small fact: "El Potton" is a reference to Alejandro Jodorowsky's film "El Topo", it's like mystical western.
And as an unexpected joke, the referenced name of this movie "potton" sounds like chilean people say "butt", I laughed a lot because the anime adaptation sounded like "Have you seen Jodorowsky's butt?". So I'm sure that scene will be posted in some chilean shitposting page.
