yes.. got a cute pink ghost from WatchTower L5.. that's all so far, but have been consentrating on upleveling the GhostCastle.
.....and a mummy from Jewelry.
.....and heaps of Dire Boars! Just wish at a crital moment like this when trying to trigger other monsters, and collecting material for upgrading Ghost Castle.. that normal critters would keep off the kingdom instead of consuming precious energy!
