A line from the DK Rap from Donkey Kong 64 is referenced in Donkey Kong's bio by mentioning "He's so strong, it isn't funny".

The game's international box art show only Mario & Sonic, while the Japanese version also features Luigi, Bowser, Amy, Yoshi, Peach, Dr. Eggman, and Knuckles.

Prior to the official announcement of Yoshi's Crafted World's title, a fake leak was posted on 4chan listing off future Nintendo games, containing the title of Yoshi's Crafted World. This leak was humorous in nature, contrasting legitimate sounding titles such as Animal Crossing: Town Founder and Paper Mario: Clay Catastrophe with obvious jokes such as Metroid: Equestrian Races and Rhythm Heaven and Hell. This led to a short-lived theory that the leak was indeed real and slid in the joke names for humorous effect. Over time, reveals of installments in other franchises featured in the leak that didn't line up would show that Crafted World was simply a lucky guess. However, some other articles from the leak, such as a multi-part DLC pass for Mario Kart 8 Deluxe, Pokémon Diamond and Pearl remakes, a Tokyo 2020 Mario & Sonic Olympics game (albeit without Pac-Man), a Switch port of Overwatch, and the at-the-time-believed-to-be-cancelled Pikmin 4 would come into fruition later by coincidence.
