Thoughts:
Green are not boss items, but reflection items.
Red are items used in battles.
Blue are items used on the board.

I still think New Pork City is returning. Ultimate Chimeras are also appearing as a trophy, making two assets from the stage as trophies. It’s also possible that the Mario Bros stage is returning, as the Side Steppers make an appearance.
