According to bizjournals.com the murals are about poop. Not made out of poop (sadly).

Regular Washington imbibers may notice something if they take an extra minute in the restrooms at the new REI flagship store in NoMa: the name of one of D.C.’s favorite bartenders, Chantal Tseng, inscribed on a roll of toilet paper held by a cartoon bear on the wall.

Washington City Paper even included her in a piece it did on D.C.’s mixologists turned chalk artists — which is how the folks at REI found her when they were looking for artists for murals at the new store.

After the call, Tseng enlisted D.C.’s go-to chalk artist, Patrick Owens, for help on the project.

Tseng and Owens drew extra animals in addition to the bear, and added leaves, animal tracks and, yes, piles of poop to the mural, which is titled “Poop in the Woods: Droppin’ Deuces Wild.” Tseng likes to incorporate haiku into her drawings, so she added a thematic one written backward that can only be read in the bathroom mirrors: “Last chance to soap up/ before heading back out there/ think of the children.”

Yes. Think about the children. And all the other folks who might get poop from your hands onto their hands or in their food.
