If you have already popped a Void Bubble and you try to pop the same one again, you’ll see a popup telling you what event prize is in that Bubble and the option to confirm your shot. If you want that prize again, confirm and pop the Bubble, but if you want something else, cancel and select a different one.
Bubbles that you have not yet popped will not give you a preview of what’s inside, and you won’t be able to see exactly which prize you’ll get from the retired NC item pool. We will, however, have an information icon you can click/tap to see which items are in the retired NC item pool!
