The great Super Nintedo RPG Earthbound had scratch-n-sniff cards in the back of the guide (oh, how I miss the days of scratch-n-sniff being exciting technology). One of the cards had a mystery smell, and if you identified the smell and mailed it to Nintedo, they would send you a Earthbound pizza flavored air freshener. These air fresheners can be found on eBay for hundreds of dollars. Why wouldn’t they?
