(Annabeth played Mario)
Princess Peach, Princess Daisy and Toad were included:
As was Bowser (and Bowser Jr.):
Plus other of Bowser's minions such as the koopa troopas and the Hammer Bros:
And a bunch of goombas:
Early in the ballet the Hammer Bros, working for Bowser, kidnapped Peach. In the meantime, Bowser Jr was after Daisy. Queen Rosaline begged Mario, Luigi, Yoshi, et al, to rescue Peach.
Mario made his way through Water World
Down a pole (doesn't look like much here, but was really difficult to stage):
Battles ensued. Many parts of the game were played out on stage, including Mario shrinking down to a smaller size (played by a young child) and being restored by the Wishing Star.
(Honestly, the first time I saw Bowser flinging Mario around like this I sort of panicked, like, "holy %&&*^$, you're about to bash her head in!")
But in the end, justice prevailed. Bowser was driven away, and all was well.
Or was it?
Overall, an incredibly imaginative, fun, show.
My part of it was making the costumes for Mario and Luigi. Also, buying various compression tubes for Mario's shin splints, since doing the Mario-style gait really did a number on her shins.
