To study these processes we analyze VLA 21cm observations of one Green Pea (GP), J160810+352809 (hereafter J1608), and HST COS spectra of 17 GP galaxies at $z<0.2$. All are highly ionized: J1608 has the highest [O III] $\\lambda5007$/[O II] $\\lambda3727$ for star-forming galaxies in SDSS, and the 17 GPs have [O III]/[O II] $\\geq6.6$. We set an upper limit on J1608's HI mass of $\\log M_{HI}/M_\\odot=8.4$, near or below average compared to similar mass dwarf galaxies.
