For some reason, I managed to breed a LOT of ethereals in my plant and cold islands. In fact I've already sold a lot of my ethereals since I have no more beds left in my castle (gold). Now I'm in a dilemma; should I sell all my other monsters and make the islands all ethereal monsters or all 4-element monsters? Which is more beneficial in terma of the number of beds and the actual amount of coins they give out?
