The seven koopalings - iggy_koopa, lemmy_koopa, larry_koopa, ludwig_von_koopa, roy_koopa, wendy_o_koopa, and morton_koopa - should all imply koopaling (or koopa_kid?) if they don't already, and from there should be a chain of implications, koopaling -> koopa -> turtle, super_mario_(series).

It's dangerous to go alone. Take this.

If you're referring to the "add" button, it's currently broken. Otherwise, the only implications I see there are bowser -> koopa, bowser_Jr -> koopa, koopa -> Mario_bros.

Hmmm.. what if there's a humanized version of one of the koopalings?

and.. what's the difference between bowser_jr who is apparently a koopa and a koopaling?

Good question. Bowser Jr seems to have replaced the Koopalings in canon. I'm not sure if "koopaling" is meant to refer to any of Bowser's children or just the original gang of seven.

I did some digging and they both seem to be acknowledge as his kids, though the relationship between koopa and the 7 seems to be downplayed a lot lately.

on the other hand, they were called koopalings... the question is, do we need a tag to cover 'the 7 of them'... or.. shoudl they all imply kooopa and be done with it?

should they even imply it at all? since they could be drawn as a human... Oh, questions...
