Quick Answer
Find Nyanchi Crunchi cereal boxes while searching trash piles. After every stat is maxed, the August 22 update says Jenny can sell a cereal box for $10,000. The August 27 patch says cereal boxes should no longer disappear while purchasing, entering or exiting the store. Boxes can contain foil cards, but no official drop rate or pity rule is published.
How to Get Cereal Boxes
Method 1 is the normal trash pile loop: search fresh piles carefully before recycling ordinary garbage. Method 2 is Jenny’s shop after all stats are maxed, using the current official $10,000 price from the August 22 update.
Trash Pile Method
The August 22 update says Nyanchi Crunchi boxes are now much more common in trash. It does not publish a fixed location, spawn interval or exact chance, so treat each pile as a search zone rather than a guaranteed cereal-box route.
Jenny Shop Method
Jenny’s shop route is a late-game option, not an early cash shortcut. The official note ties the $10,000 purchase to maxing every stat first, so having $10,000 alone is not enough if your stats are not maxed.
August 27 Store Bug Status
The developer says cereal boxes no longer disappear when purchasing, exiting or entering the store. Treat this as the current official bug status, not as proof that every future store edge case is impossible.
Fastest Way to Get 10 Cereal Boxes
For Gacha Addiction, clear piles consistently, pick up visible valuables before generating a new pile, and switch to Jenny purchases once all stats are maxed. Keep a simple count of boxes opened and note whether each came from trash or Jenny.
Can Cereal Boxes Contain Foil Cards?
Yes, the Steam store description connects unopened cereal boxes with super-rare foil cards. That does not mean every box is foil, and the official sources do not publish a foil percentage.
Achievements Tied to Boxes
Just Don’t Eat It! requires opening one cereal box. Gacha Addiction requires opening 10 cereal boxes. If your personal count and Steam achievement state disagree, preserve your save and record the source of the box before troubleshooting.
Why Did My Cereal Box Disappear?
This was addressed in the August 27 patch for store purchase and store enter/exit cases. If a box still disappears on a later build, preserve your save, record whether it came from Jenny or trash, and note the exact transition that removed it.
Current Unknowns
The site now treats $10,000 as the current official Jenny shop price for the documented August 22 build and the store disappearance fix as the current August 27 status. Drop rates, fixed locations, pity counters and guaranteed foil behavior remain unknown.
