They can leave water, and walk on land with legs if they stay dry. (think H20 or the movie splash)

Honestly, as far as I go - though I'm not Emma - I don't think it quite matters if we get another Witch. I'm plotting out another character that isn't a witch - either a shifter or perhaps a vampire. Maybe a fae or dragon, but probably not. 
We can always fill in with other species as the RP goes and others get interested.
