Compare the two costs
| Choice | Immediate result | Cost to your run |
|---|---|---|
| Dig for Valuables | One Leftovers and one Shell Bell, subject to item application limits. | Black Sludge raises shop item and reroll costs to 2.5 times their normal price for the rest of the run. |
| Investigate Further | A boss battle against Gigantamax Garbodor. | The fight starts with Toxic and Stockpile effects, and the boss has an extra health segment. You must survive before choosing a reward. |
Favor investigating when your team can handle the battle and still needs its money for later healing or rerolls. Favor digging only when avoiding that immediate fight is worth the permanent price penalty and the healing items materially help your plan. A damaged team can make the battle dangerous; a cash-poor team can make the penalty dangerous. Neither option is universally free value.
Estimate the price penalty before digging
Use the prices currently shown in your run as a baseline. A future purchase that would cost 1,000 would cost about 2,500 under a 2.5× multiplier: 1,500 extra. For a planned set of purchases with normal total cost B, the extra burden is about 1.5 × B, before other price modifiers or rounding.
This is an arithmetic example, not a measured shop price. Apply it to your likely remaining healing and rerolls, rather than assuming that an Amulet Coin or Golden Punch automatically cancels the penalty. Those items do not make every possible future purchase affordable.
The penalty lasts for the remaining run. Do not take the healing items expecting a biome change to reset shop prices. Also check who can receive the items: the release code checks held-item limits, so a full stack should not be treated as another guaranteed useful copy.
Prepare for Garbodor’s opening
Investigating reveals Gigantamax Garbodor. In the checked release it opens with Toxic against your side and Stockpile on itself before normal move choices. Its move set is Gunk Shot, Stomping Tantrum, Hammer Arm and Payback; it has one additional boss health segment.
Before choosing, consider whether your available team can take that opening and finish a shielded fight. Do not judge the route only by Poison typing: its listed attacks also cover Ground, Fighting and Dark. This is a readiness check, not a guaranteed counter build or an assertion that every opening move always lands.
After victory, the reward selection includes Leftovers plus Rogue-, Ultra- and Great-tier options. These are choices on a reward screen, not four items automatically awarded together. The fight route therefore does not promise the same immediate Shell Bell as digging.
Recognize this encounter and its limits
Trash to Treasure is eligible from wave 100 within the Mystery Encounter window ending at 180, needs at least three party members and appears at most once per run. The checked code exposes investigation and digging; it does not offer a standard free “leave” option. Do not confuse Black Sludge’s encounter penalty with an ordinary held-item recommendation from another Pokémon game.
