I came across a mention of Maurice Sendak's "Where the Wild Things Are" and thought it'd be a great title for a meta. I think the mechanism is standard but has a slightly original twist to it. But the grid fought me all the way.
So. LET THE ..... well, you know.
First nudge. Two of the entries are hints to the mechanism. As well there are several themer entries
Nudge two. It's not the answer to the two hint entries that are the hint. It's the clues.
Nudge 3: In nudge 2, I wasn't really considering 25D or 56 to be hints. (The hints and the themers are all across entries). But, yes, The Title says it All. You most figure out where the Wild Things Are. And one of the across clues tells you exactly where they are As well as what they are
Nudge 4: 10A is one of the key hints. "Let the wild rumpus start!" was a key phrase from the book. There are three odd things about this entry Why is RUMPUS in all caps? If the answer is WILD is it kosher to include the word "wild" in the clue? Well, there isn't too much to this. I just wanted to make sure this entry was meant to be a hint is all. Wait? Isn't it "Wild Things "? Why did I write "wild animals"?
Nudge 5:Okay, enough about the two hint entries (while I've only talked about one hint entry but if you found one the other should match), you still need to find the themers. How do you find the themers? Well, I've already told you how to find the themers, and what to look for in them.
Nudge 6: I went to the wild corners of the earth to foreshorten Thrace
