Dorayaki
King Bowser
Luma made its very first spinoff main role as Rosalina's buddy back in MKWii, and then joined Smash bros as Rosalina's teammate. However, for unknown reason we don't see Luma too much often in recent new games.
One reason could be it takes extra time and budget to make Luma following in every single game (especially in Mario Party, it would be really tiring for programmers to locate Luma in every single mini-game.) However, even if Nintendo don't want to dedicate to Luma in main gameplay, adding Lumas to the event staff along with Toads and koopas can also be an option.
Another reason could be that Luma would bother gameplay like occupying the screen when you need to watch the courses carefully.
I think despite of Rosalina's incredible popularity today, her whole character is being Luma's guardian and it feels kinda.... not so corret for her to keep Luma at home in most games. I also think Luma would had been a very cute mascot addition to the main cast.
Do you think Nintendo could had treated Luma better?
