An unknown zine writer struggling with mental illness and various forms of existential crisis tells his story via a disorganized hodgepodge of dreams, memories, rants, philosophical scraps, reviews, college papers, poems, anecdotes, musings on cosmology and the social sciences, and other stream-of-consciousness detritus. Platypus is an awkward and disjointed memoir that attempts to exorcise the author's personal demons as he struggles to come to grips with the world by way of words and ideas.
