So far I've found three items: two N Scale baseball "gift sets" and an animated fisherman. The products are not cheap; the baseball sets are around $60 each, and the fisherman is $125. There could be any number of these products floating around out there. Images are thumbnails scrounged from Google searches.
Where to Buy
Given that none of these items appear in their website—indeed, there's no mention of N Scale at all—I believe the likelihood of finding any of them is very close to zero.
