Toxic Sponge quick answer
Toxic Sponge is a hazard flora entry associated with Blighted Coral. Treat it as a route marker first and a harvest target second; many bad plant routes start when players gather before they know the recipe need.
| Field | Notes |

| Main region | Blighted Coral |
| Type | Hazard flora |
| Scan or harvest method | Scan at range and avoid lingering in the cloud. |
| Main use | Hazard marker, plant log |
| Risk | High |
Location and route
Approach Toxic Sponge from a known oxygen point, scan the plant, then check the floor, walls, and nearby fauna before harvesting. If the plant sits in Blighted Coral hazards, mark it and return with the right tool instead of forcing the route.
Uses and unlock value
The practical value is hazard marker, plant log. If it supports a recipe, collect only the amount needed for the next craft. If it is a landmark, use it to label the route and connect it to the nearest biome or resource loop.
Risk and scan notes
A clear reason to upgrade route discipline. In co-op, call out the plant name, region, and nearest return marker so teammates can reuse the route without duplicating the scouting work.
