Hightail Falls are another popular tourist attraction made even more popular by Mario's escapades. Tourists were already spoiled for choice to begin with: you could go swimming at the bottom of the falls, explore the top of the falls, go for a peaceful walk alongside one of the many rivers that snake along the countryside, or visit the Lake of Infinity, from where all waterfalls begin.
Or, you could recreate the route Mario took, with several redesigns to make it safe for tourists, and no Yoshi.
The Lumas had insisted on it, wanting to relive Mario's moments of glory and triumph, wanting to be Mario, the hero with many tales and gifts of thanks to his name. It was practically their hobby at this point.
Rosalina couldn't help but smile at their starry-eyed lens through which they looked at the plumber. He had genuinely inspired people to be a hero, and if not, then the best version of themselves they could possibly be.
And if the Lumas took that philosophy with them wherever they go, then that would be wonderful.
But that in turn led the Lumas to want to constantly leave to go on grandiose adventures they clearly weren't capable of handling (if the amount of times they had to be rescued by Mario was any indication). They were willing to put themselves in danger for a fleeting moment of heroism.
Rosalina had tried to teach them things all their lives. Now, she was trying to instill them with her wisdom even more so: lessons about serenity, kindness, patience. Especially patience. Good things come to those who wait.
Patience is a virtue, and it really is.
The Lumas would need to be patient about when they would transform into a star or planet. And when they were ready, Rosalina would see them off with a smile. They would engulf themselves in a bright light and reemerge a changed being.
Someday, somewhere, a person will see the gorgeous surface of the planet, or the light cast by the star, and smile at its timeless beauty.
That would be a moment of glory and triumph, albeit subtle: making someone smile, giving them a moment of happiness, whether in a time of darkness or light.
Giving someone something to be happy about. No matter the occasion.
Rosalina would have to try harder to teach the Lumas that.
