Bubble Bath Madness

Upon arriving at Beth's Baths, the group found foamy bubbles escaping from around the edges of the door frame. The front of the building had no windows, just a reinforced wooden door with a swinging sign above that reads "Beth's Baths".
Upon opening the door, a torrent of bubbles erupted from the building, obscuring anything on the inside. Screams were heard from within.
The bathhouse had recently received some new bathtubs, two of which were mimics. The mimics had reacted to some of the bath soaps, creating a mass of bubbly madness. The mimics were in the bathhouse's public bath area, and were attacking bathers who are trying to blindly escape.
Naked people everywhere.
