The Manchineel Tree (Hippomane mancinella)

Introduce the world's most dangerous tree to coastal and swamp biomes. This tree is not a resource, but a pure environmental hazard that tests the player's "Nature Literacy."

The Lethal Fruit: Unlike other crops, the "Apple of Death" cannot be made safe to eat. In line with its real-world counterpart, no amount of peeling or cooking can remove its toxicity. Attempting to consume it will always result in fatal poisoning.

Environmental Danger: During rain, the water dripping from the leaves becomes acidic. Players standing under the canopy take consistent acid burn damage.

The Smoke Hazard: Burning the wood is not a solution. It releases toxic smoke that causes a long-lasting Blindness effect and respiratory damage (poisoning) to anyone nearby.

Manual Handling Risk: Chopping the tree with an axe splashes toxic milky sap onto the player, dealing immediate damage. The only way to safely clear it is through careful, distanced interaction or protective gear.

Conclusion: The Manchineel tree is a true "Nature Literacy" test. It teaches players that not everything in the wild is a resource — some things are simply meant to be respected and avoided
