The meta is pretty straight-forward (although it may be a little hidden and hard to spot) and nothing unique or original, although the context certainly is.
Nudges:
1: The themers should be pretty darned obvious
2: The themers are the long entries that are silly puns about animals
3: So you found them. What do you do with them?
4: So the themers are puns. What are they puns of?
5: So do something with what the entries are supposed to be
6: Find things that have to do with those words or phrase
7: What's another way of saying hypocrisy, felicity, significant, etc?
8: You can find those other ways somewhere, can't you?
9: This is a very standard metanism. Probably one of the most common there is.
10: E. Nigma was the name of the Riddler in "Batman". The authors were making a pun. What does the word "enigma" mean?
11: What's a common insult for a hypocrite? Who was the Bard of Avon? Who was the Vulgate Bible written for? etc.
