By the way -- if you manage to get your hands on the Afternoon Tea Set DLC item, consider carefully before trading it. Nintendo has said that once you get the item, you won't be able to get it again either by ordering it from your catalog at Timmy and Tommy's, or through visiting another Nintendo Zone at a future date.
There will be at least one more SpotPass DLC item coming up in the next couple of weeks, so don't miss out!
