As my head is still filled with mucous I had Bruce confirm it: only 5 Spice-colored Finsters were in the Finsterium. Either two had escaped, or they were hiding inside a nest box. Since the Spices are so dark we had to use a flashlight to confirm it (d*** flashlight) which of course scared them out. But they found it all right! The hybrid and a Spice were inside a nest box.
