|"Oh ... so you wanna play dirty, huh?"|
|— Katara threatening Toph preceding their confrontation.|
"Dirty Is Only Skin Deep" is a comic book that takes place in Book Two: Earth, originally released by Nickelodeon Magazine. It was later recycled for Free Comic Book Day 2011, and was finally re-released by Dark Horse Comics in Avatar: The Last Airbender — The Lost Adventures.
When Team Avatar notices that its new recruit, Toph, is less than clean, Katara will do whatever it takes to wash her down.
While bathing and cleaning her clothes in a lagoon with Aang and Sokka, Katara asks Toph, who is stomping around in the dirt and singing, if she wants to join them in the water. Despite criticism from Sokka, who wonders if the smell was as beneficial as the dirt covering her, Toph refuses to get in the water. Katara responds by pulling Toph along herself into the water, but the earthbender bends a wall into which Katara collides. In a last-ditch effort, Katara lifts Toph into the air with her waterbending and drops her into the lagoon. Instead of protesting as she had before, Toph merely flails in the shallow water, shouting that she does not want to drown. Pitifully, Katara parts the water so that Toph will stop screaming. Falling into the mud that lay at the bottom of the lagoon, dirt flies onto the clothes that Team Avatar just cleaned as well as Toph's friends. Although Aang tries to infuse humor by mentioning their "protective layers of earth", Sokka sarcastically mentions how the Fire Nation will not be deterred by "mud in their eyes".
