Just in case you didn’t know or realize it, when Nick aired the episode “The Guru”, they left out the location of the water chakra because of where it happens to fall on human anatomy. It’s always been something of a joke to the Avatar community, resulting in several memes and gag comics. We had to have TaN take a crack it, too.

We can definitely see the differences in ages and the knowledge that comes with time and experience in this panel!
