How will Bowser get back home?

Bowser, Peach, Kamek, and the Toad Brigade had no clue to get to the Koopa Kingdom as they were lost, cueing the end screen as if this episode was left on an unresolved cliffhanger until Blue Toad uses the Starshroom that he built that will enable them to return to Bowser's Castle, adding an additional fifteen minutes to the story.
