  The first known interstellar object, 1I/2017 U1 'Oumuamua, displayed such
unusual properties that its origin remains a subject of much debate. We propose
that 'Oumuamua's properties could be explained as those of a fractal dust
aggregate (a "dust bunny") formed in the inner coma of a fragmenting exo-Oort
cloud comet. Such fragments could serve as accretion sites by accumulating dust
particles, resulting in the formation of a fractal aggregate. The fractal
aggregate eventually breaks off from the fragment due to hydrodynamic stress.
With their low density and tenuously bound orbits, most of these cometary
fractal aggregates are then ejected into interstellar space by radiation
pressure.
