Turns out that the Ghazt and the Jeeode can be put into the Love Shack together, but since there is no Plasma/Crystal hybrid, they just make more little Ghazts and Jeeodes. Handy for populating the island and getting shards until I get the other one-element ethereals.

Although as has been pointed out elsewhere, Shards don't have a lot of use, after clearing the landscape, buying a few decorations and structures, and upgrading the castle.
