Lucky sunk down into the foamy water, not exactly sure what she was supposed to be doing. But the natural flow quickly filled the water with thick foam, smelling like a car wash. “Get your wings in it!” Lightning instructed. “Cover both of them as thick as you can, then I’ll help with the brush. See the clip on the wall there? If you don’t have anypony else with you, you put the brush there and rub up against it. But my shift is in an hour, so… we don’t have time for that.”
