Kirby's Return to Dream Land Deluxe redesigns Wing Kirby's costume, changing the pattern on the headband to a series of straight lines, adding a red jewel on the front (similar to the kind seen on other Copy Ability hats), and replacing the rows of feathers on the back with arrangements that more closely resemble a bird's wings. As the original design was based on a Native American warbonnet, the redesign was likely to avoid cultural appropriation, as real-life warbonnets are regarded as sacred in tribal cultures and consequently can only be worn by those who have earned the right to do so.

In modern iterations of Fighter Kirby's moveset, the charged attack Instant Mega Blast uses the same key combination as Ryu's Hadouken from Street Fighter, likely meant as a tribute to the series.

When Kirby's Return to Dream Land was localized in Europe, the title name was changed to Kirby's Adventure Wii and has the same box art from the Japanese version, rather than the box art from the North American release. This name change was not carried over to the Nintendo Switch version and was released with the original Return to Dream Land name.
