I rebuilt every Vahki except for the green one! The one problem is that the black one wields a spare pair of the blue one's weapons, but that doesn't matter to me! Surrender or run!
I never tried to memorize Vahki or Visorak names. Bohrok and Rahkshi were simple, but the next two sets of villains were confusing. Let me give it a try, in order Red Blue Green Brown Black White. (I'm not looking)
