If you like shoes, and all things foot related, you might want to take a look at the Best Foot Forward hunt. This hunt has 27 stops so you can probably go from start to finish in a couple of hours. Look for the black shoe prints.
Is your avatar too tired to run around? You might try out the Marketplace Hunt. That’s right, you don’t actually have to “go” anywhere… just jump around the Marketplace looking for the items tagged for the hunt. Pretty clever actually.
There are plenty of other themes of course. Check out the list!
