Dirty Is Only Skin Deep

Dirty Is Only Skin Deep is a comic that was released May 7, 2011 by Dark Horse Comics in honor of "Free Comic Book Day".

Overview
Katara has a hard time getting Toph to bathe.

Synopsis
Sometime during their journey, Team Avatar decides to lounge in a secluded Earth Kingdom lagoon. While there, Katara, Sokka and Aang use the opportunity to bathe themselves and wash their soiled clothes, though Toph simply sings melodies about Badgermoles, refusing to wash herself. Katara urges Toph to join the rest of them relax in the water, but Toph declines the offer, stating that a healthy coating of earth is beneficial for any Earthbender. Leaving her no choice, Katara Waterbends Toph, suspending her in the air before placing her in the water to soak. Toph panics, exclaiming that she was not proficient in swimming, and that she was drowning. Katara splits the water to allow Toph to feel solid ground. Toph wriggles in the mud, soiling everybody's clean attire, much to Katara's dissatisfaction.
