  The dwarf irregular galaxy HIPASS J1131-31 was discovered as a source of HI
emission at low redshift in such close proximity of a bright star that we call
it Peekaboo. The galaxy resolves into stars in images with Hubble Space
Telescope, leading to a distance estimate of 6.8+-0.7 Mpc. Spectral optical
observations with the Southern African Large Telescope reveal HIPASS J1131-31
to be one of the most extremely metal-poor galaxies known with the gas-phase
oxygen abundance 12+log(O/H) = 6.99+-0.16 dex via the direct [OIII] 4363 line
method and 6.87+-0.07 dex from the two strong line empirical methods. The red
giant branch of the system is tenuous compared with the prominence of the
features of young populations in the color-magnitude diagram, inviting
speculation that star formation in the galaxy only began in the last few Gyr.
