Once Upon a Who? introduces the central themes of the artist's Who the Bær project. Screened as part of a custom-made environment, the stop-motion animation presents Who, the original cartoon figure created by Fujiwara. Created in a process of stop-motion–placing the cut-out elements from one frame to the next to create the illusion of movement–Once Upon a Who? recalls early film animation, yet also addresses topical issues relating to the contemporary digital media.

The simply executed but visually striking animation is accompanied by a soundtrack that includes a text, performed by the artist: intoning the poem-like verses, at times with a humorous undertone, at times even half-singing, the artist highlights the mock pathos of his tale.
