On the other hand, the scene afterwards where
the next Koopaling in line (this case Morton) captures her is pretty clever, more interesting than just Bowser Jr carrying her from castle to castle and somewhat more logical.
Because as it is so far, it really does look like Nintendo is taking a lot of influence from Super Mario World in respect to what things return in the
next two New Super Mario Bros games, now with the
Koopalings, Reznor, Yoshis, Clown Car and various other things.
