SlipperyFishes alternates two letter sets to create an undulating line of text that reminds me of a slippery fish. It resembles Undulate, another typeface that uses the OpenType feature of contextual alternatives (calt) to alternate letters, but while the tops and bottoms of letters in Undulate trace parallel paths, the tops and bottoms of letters in SlipperyFishes trace reflecting paths.
SlipperyFishes has monospaced with tight letter spacing to accentuate the ripple pattern. The family has four members: regular, outlined, condensed, and condensed outlined.  The outline styles that can be used in a layer with their base styles to add color. Slippery fishes is bizarre and weird and can be used in places where those attributes will create attention-grabbing lettering.
