... and I know I really shouldn't, but I just couldn't resist.

Hope that helps with the mental association problem.

I thought it probably wouldn't be necessary, but I wasn't certain, and I figured it would be the better part of valor. Basically, I'm not sure how to proceed under the declaration that the identity of an extremely central character is supposed to be a spoiler now; it seems like even using the name Dhveeryzbeg unscrambled would break the rule.

I didn't make the Zoidberg connection until you pointed it out, but I did think that "D-Zbeg" was an immensely more awesome nickname than the term it was rot13'd from.

And now I can't see "Dhveeryzbeg" either without thinking it must be some relative of Dr. Zoidberg's. Dangit, now every scene he's in, I'm gonna expect him to exit going "woo-woo-woo-woo" and clacking his claws.

I think this or something very close to it is strongly likely to be correct; so much so that at this point, I'm very close to shifting the question to the level of whether, univat tebbzrq Uneel nf n fgebat prageny yrnqre sbe zntvpny Oevgnva, uvf vagragvba vf gb npgviryl pynvz cbffrffvba bs Uneel, be jurgure ur jvyy or fngvfsvrq nf gur cbjre oruvaq Ehyre!

The fact that you haven't seen a tiger in your trashcan is, however, evidence that there is no tiger in your trashcan.

Edit: Which I think is more or less harmonious with your original post. It appears to me, however, that at some step in the discussion, there was a leap of levels from "absence of evidence for goblins in the trashcan is evidence of absence of goblins from the trashcan" to "absence of evidence for goblins in the trashcan is evidence for the complete nonexistence of goblins".
