Reddit mentions of Chocolate Animal Crossing for Nintendo Tobidase Hardcover Kisekae 3DS LL

Sure! Mine is the first, and I added in some others that I found too:

Case 1

Case 2

Case 3

It's an import from Japan but fits my 3ds XL just fine!

Like LadyDrac mentioned, there will be a new 3DS out soon that has animal crossing swappable faceplates. In the meantime, you could try a skin like this:
