Well, I noticed that Zoog Burrow has a Zoog resource icon but its text doesn't mention any effect related to draining the domain it's attached to.
Since the FAQ says that "A card attached to a domain as a resource does not have a text box, unless the card has a Zoog icon", it's clear that the card counts as a Dreamlands location even if it's attached as a resource.
But does it also mean that you can trigger its Response while attached as a resource? It seems odd that you can exhaust a resource...
