I will describe how we are using WIYN+HYDRA to study ultra-strong emission line galaxies (rest-frame EW(Hbeta) 〉 30A). This population contains some of the lowest metallicity galaxies known (12+log(O/H)=7.1) and offers the potential for determining whether there is a metallicity floor on late forming galaxies.
