I really like this because it implies Dedede’s monarchy has a history, and it makes sense for his character of a greedy (but ultimately very lazy and pretty harmless) king, he never took his position by force, he just always assumed he was always supposed to be king, and Dream Land sort of goes with it.
Wario and Waluigi’s elf-ish ears are a detail of their characters that I’ve always found fascinating. Like, there’s so many possible implications when you assume that Mario and Luigi are just italian plumbers who happened into the world of the Mushroom Kingdom by chance. Do they come from some bizarro mirror world, are they the Mario and Luigi from this twisted world? Or are they some sort of other creature that’s bent on stealing Mario and Luigi’s identities, and their identities of Wario and Waluigi are constructed and fake? Are they some sort of identity-snatcher gremlins? Is this their original form, or are they shapeshifters?? What magical powers and weird properties do they have, knowing they’re not human?? I genuinely love thinking about these ideas, I wish the Mario series would get a bit more fantasy and fairy-tale weird like that
