Hm, I'm not sure? I got a Wubbox on Plant Island, and am currently saving up for one on either Cold or Air Island (not sure yet which I'll do first). I didn't see an option to give the Wubbox the Ethereal or Legendary monsters on Plant Island, only one of each Natural monster. I'll look into it in a day or two when I have enough coins to buy another.
