These are Sega Joypolis Sonic Biscuits. They're too thick to be a cookie, so they were probably aiming for cake-like. However, if you read the magazine blurb here, you'll see that they missed. When something uses the phrase "Never Ending Bean Cakes", you can tell you're headed down the wrong track. It doesn't say how many heads you could get for the 5 bucks. However, the reviewer finds them quite bland. These were an early Dreamcaste-era released food. Wonder what they were trying to taste like, but missed?
