Donald discovered a Minecraft-like world in a story called Lost in the Andes! Donald and his nephews stumbled upon an isolated city called Plain Awful, where, like Minecraft, absolutely everything is made of blocks, including buildings, rocks, animals, and hills. Even the people are blocky and have managed to create clothes that are almost completely square, meaning that in terms of aerodynamics, they are the slowest people on Earth.
"For the love of God, move me faster; I'm literally going to shit a brick."
It's not just that things are square, though; there are weird similarities between the culture of the Donald Duck square-world and Minecraft. For example, one of the main activities in Minecraft is, well, mining, which, sure, is a little on the nose, but it's also the main pastime of the folks in Plain Awful, and where they sentence Scrooge to do hard labor after he brings a circular object into their city.
"Congratulations, you just devoted 200 hours of your life to a digital activity
that is considered a punishment in both real and Scrooge McDuck life."
