Sewer-hole inspection is an Expert Nature habitat that uses 4 material types and 4 total pieces. It is best treated as a focused layout rather than a generic decoration cluster.
The full recipe for Sewer-hole inspection is Traffic Cone ×1, Sewer-Hole Cover ×1, Excavation Tools ×1, and Iron Pipes ×1, totalling 4 stacked items across 4 distinct materials. Traffic Cone is the largest single ask in the recipe at 1 units, so treat that one as the gating material when you plan farming routes — locking down a daily collection loop for Traffic Cone usually unblocks several adjacent habitat builds at once, not just this one.
Sewer-hole inspection attracts Poliwrath, Corviknight, and Tinkatuff. Because Pokémon visits are habitat-bound, the moment this build is placed the entire roster above becomes eligible to drop in on the right time-of-day and weather windows. That cluster behaviour is what makes habitat investment pay off — one recipe, multiple Pokédex pages cleared.
Sewer-hole inspection is rated Expert difficulty in the Nature category. Expert habitats are the deepest builds in Pokopia — recipes pull rare, region-locked materials and the visiting roster includes Very Rare entries. Treat them as long-haul goals, not weekend projects. Nature habitats lean on raw outdoor materials — wood, plant matter, basic stone — and tend to attract Grass, Bug, and Normal-type visitors. They're the densest category in the catalogue, so most clusters of habitats you'll see in town are Nature variants.
Once Sewer-hole inspection is up, the natural follow-ups in the same Nature category are Tall grass, Elevated tall grass, and Riding warm updrafts. They share the broad material family and the visiting Pokémon types overlap, so each successive build extends an existing farming route instead of starting a new one — that's how you compound habitat investment without spreading materials too thin across the map.
Rebuild this setup by matching the exact material mix below. Tight material counts matter because many Pokopia habitats overlap visually but trigger different attraction pools.

Sewer-hole inspection's recipe calls for Traffic Cone ×1, Sewer-Hole Cover ×1, Excavation Tools ×1, and Iron Pipes ×1 — 4 stacked items across 4 distinct materials. The biggest single ask is Traffic Cone at 1 units; lock down a daily route for that one and the rest of the recipe usually follows.
Sewer-hole inspection attracts Poliwrath, Corviknight, and Tinkatuff. Building the habitat once opens visit windows for the entire roster, so plan around the cluster rather than chasing a single entry.
In the same Nature category, the natural follow-ups after Sewer-hole inspection are Tall grass, Elevated tall grass, and Riding warm updrafts. They share the broad material family and overlap on visiting Pokémon types, so each successive build extends an existing farming route instead of starting a fresh one.
