Before you can draft a dragon into doing Locktober, first you need to explain the Gregorian calendar, then explain the English pun, then explain what non-dragons decided the pun means, and only at that point can you start to tempt them with how good they'll look in the belt and how fun it could be~ Fortunately, the last bit can be pretty easy with dragons, just make sure you come prepared if they start musing about what else could feasibly be locked all month long...
