How Tracy upgrades work in practice
Tracy is an NPC you progress by sending her cats that have reached five years of age, which is simple to plan around because aging happens through the normal daily cycle. Her reward track rotates between Food Storage Box, Blank Collar, and special Idol Furniture, so you generally keep feeding her eligible cats until the specific item you want shows up again.
How to get the Food Storage Box upgrade
Food is consumed every daily cycle, so raising your storage cap matters most when your house population grows and you start bringing back larger hauls from expeditions. The Food Storage Box is the cleanest permanent solution because it directly increases your maximum food capacity and can be placed like other furniture.
Step 1: Let a batch of cats reach age five
Tracy only takes cats that are five years of age or older, so pick the cats you do not plan to keep for breeding or late-game runs and simply let time pass naturally.
Step 2: Donate enough eligible cats to hit the next reward tier
For the Food Storage Box tier specifically, Tracy needs 10 cats that are five years of age or older to unlock that next reward tier.
Step 3: Buy the Food Storage Box when it appears in her wares
Once available, purchase the Food Storage Box from Tracy for 100 coins; if you cannot afford it immediately, it should remain in her wares on later days while you earn more money.
Step 4: Place it in your house to apply the bonus
Open the Furniture menu and place the Food Storage Box anywhere that fits; once placed, it increases your max food capacity by +40.
Step 5: Repeat as needed for a higher cap
Because the Food Storage Box is an item you can keep purchasing, you can continue cycling Tracy rewards and buying more boxes over time to raise your cap further.
How to use the Blank Collar upgrade for duplicate classes
Blank Collar is a Tracy reward that increases your options during class selection by adding extra collars, which is what enables duplicate classes in a single adventure run. In other words, it is the gateway to compositions like double support, double damage, or any other stacked setup you want to test.
Step 1: Progress Tracy until the Blank Collar rotates in
Her rewards alternate among Food Storage Box, Blank Collar, and special Idol Furniture, so you may need multiple donation cycles before Blank Collar appears.
Step 2: Purchase the Blank Collar when it is available
When Tracy offers it, buy it so it is available as an additional collar option during class selection.
Step 3: Build your party with duplicates during class selection
On the expedition setup screen, use the added collar options to select two or more of the same class for the same run.
How Idol Furniture upgrades your home setup
Tracy can also unlock special Idol Furniture, described as objects you place in your home that have boosted stats or special effects. These are long-term power pieces: you buy them once they show up, place them, and they contribute passively to how your house performs day to day.
Step 1: Keep donating five-year-old cats until Idol Furniture appears
Because her rewards rotate, you will eventually see the special Idol Furniture option after enough cycles.
Step 2: Buy the Idol Furniture from Tracy and place it at home
Once purchased, place it in your house like other furniture so its boosted stats or special effects are active.
Rewards from Tracy
| Reward from Tracy | Type | Benefit summary |
|---|---|---|
| Food Storage Box | Home utility item | Raises max food capacity; placed in house; +40 max food per box |
| Blank Collar | Collar-related unlock | Adds additional collars during class selection so you can run multiple of the same class |
| Special Idol Furniture | Home furniture | Placeable items with boosted stats or special effects |
If food feels tight, start by pushing toward Food Storage Boxes so you are not stuck under the default cap and can safely bank larger totals. If your runs feel limited by party roles, aim for Blank Collar so you can bring duplicate classes and tune your team for specific problems.
