Ninjis in a casino
Peach, in action movie fashion, fights an army of Ninjis in one scene in the trailer. Ninjis first showed up in Super Mario Bros. 2 (or Doki Doki Panic, technically), and they recently reappeared in Super Mario Bros. Wonder, most prominently in the Ninji Jump Party level.
The battle appears to take place on top of a giant roulette, so this locale might have inspirations from a number of places in the Super Mario series, including Casino Delfino in Super Mario Sunshine or perhaps even Luigi’s casino in the Super Mario 64 DS minigames.
