Biohazard

Biohazards are a type of hazardous collectible in Pikmin: Neo. They are strange substances found deep underground created by the unstable crust of Hoco-Minor. They take the form of multicolored stones with a bumpy texture and smoky complexion. Biohazards start appearing in the game after either 30 days are spent on the planet or two separate sanctums are destroyed and their resident boss monster is killed. Biohazards are dangerous as they can completely change the climate of the local area they reside, such as a formerly scorching desert becoming a freezing artic forest. This change in climate also changes the types of enemies that spawn causing rarer, more dangerous enemies to spawn outside their home biome. Due to this biohazards need to be neutralized as to avoid a ecological catastrophe. Unfortunately biohazards are radioactive, meaning that even if your dig them up the radiation will choke and kill any nearby Pikmin. The only Pikmin who are immune to this radiation is Bone Pikmin whose calcium shells makes them able to absorb the energy safely. Biohazards make a great source of Sparklium so hunting for these items would be a good opportunity to make a profit.
