Consequence of charging the Odyssey before visiting boss level? [duplicate]
If you go back to the top of the inverted pyramid, the Broodals' ship will appear and challenge you to a battle as normal.
Everything else in the level should be exactly the same as it was before Bowser's ship left.
The one exception is if you have completed the story, the underground section will contain the oversized wedding ring. This doesn't make a difference to any gameplay, however.
