i can breed you a whismur, but the rest should be available for you. You should definately check out the under water section of azurine lake. This is a nice sidequest and you can find corsola(in houses i think), frillish, eelectrik(1% outside houses), meranie, wimpod, dhelmise and i also guess relicanth(not sure). Also for dewpider you need to do the nothern part of the heracross/pinsir puzzle. Hawlucha should be obtainable on route 2 in the morning. Surskit is to be found in coral ward. And these are only the ones i know without looking anything up.
