Recently, I tried to name a pet 'Cumulus' - like the cloud - and was told that it was inappropriate. All right, that one I guess I kind of understand. It's got the word 'kitten' in it. A little excessive, but I get it.
Then I tried to name my wolf Gmork, like the wolf from the Never Ending Story - but that one was also inappropriate. ... why? I genuinely can't figure out why that one is disallowed. Am I missing something here? Is it because it's copyrighted? But I could name my warthog Snuffleupagus without issue.
