Teleporting them to Ethereal Island removes them from the original island completely. You can't place them on Gold Island - they appear in the list of monsters to place, but they're greyed out and can't be selected. They teleport as an egg in the hatchery on Ethereal Island (though fortunately it doesn't take as long) but they revert to level one.
