The current cereal-box route

Nyanchi Crunchi boxes can appear while you clear trash. The August 22 update says they are now much more common, and it also adds a dependable late-game purchase route: after every stat is maxed, Jenny sells a cereal box for $10,000.

The shop condition matters. Reaching $10,000 by itself is not enough; the official announcement ties the purchase option to maxing all stats first.

Plan Just Don’t Eat It and Gacha Addiction

  1. Open the first box for Just Don’t Eat It.
  2. Keep a simple count of boxes opened toward the 10-box Gacha Addiction requirement.
  3. Clear each active heap completely and collect loose items before asking Jenny for another heap.
  4. If you are close to max stats, compare the final upgrade spend with the repeatable $10,000 shop route.
  5. Treat any foil as a separate result; opening a box and receiving a foil are not the same counter.
Keep in mindCurrent player reports say loose collectibles can disappear when another heap is activated. Pick up the cereal box—and every visible card, tape, figurine, and outfit—before starting the next heap.

Why some older answers say $50,000

A pre-update Steam discussion records the old $50,000 shop price. The newer official August 22 announcement explicitly changes the price to $10,000, so the lower figure is the current published value.

The update does not say whether a box purchased from Jenny advances Gacha Addiction. Until the game or developer states that rule, use the achievement notification rather than assuming every acquisition route counts.

Keep in mindNo current official source provides a cereal-box drop rate, fixed trash location, pity counter, or guaranteed foil result.

Where can I find cereal boxes in KOTAMON?

They can appear in trash heaps. After all stats are maxed, the current patch also lets you buy a box from Jenny for $10,000.

Are cereal boxes still $50,000?

No. That was the older community-reported price. The August 22 official update states a current price of $10,000 after all stats are maxed.

Does every cereal box contain a foil card?

No guarantee or drop percentage is published. The official store says a box can contain a super-rare foil card.
