Isn't your other Pokemon a sea horse? Shouldn't you put that one in water as well? Or maybe the best idea would be to put them in the balls seeing as it seems to be an universal container for all Pokemon types... but wouldn't that mean there has to be water in them and how would the fire types react to it...
