I finally understood the true age order of koopalings.

Let's start with the fact that koopalings stopped being bowser's children after SMB3 and SMW and started being just browser's henchmen in NSMBW. So Nintendo could have changed their ascending order and shown a new ascending order in NSMBW, and SMB3 is their old ascending order.also in NSMBW, Larry is the first and Ludwig is the last, so this is how the age order of koopalings should be: 1. Larry. 2 roy. 3. Lemmy. 4. Wendy. 5. Iggy. 6. Morton. 7 Ludwig.
