Ah, the happy memories. These are the best things in your entire existence. You can also just leave the orbs laying haphazardly around, and they automatically make a lot of juice, but with some special equipment, as well as a pinch of sad syrup, you can produce the most amount of juice possible.
Not only that, but these are the reason for collecting juice in the first place. What purpose would existence have for you any more without plenty of these around?
