The Rainforest Tree is the main tree type which can be found in the Hamlet DLC. There is 3 different versions of it, each with different names, appearance, and loot.
This tree is renewable, but only in the Lush season, when it blooms.
All kinds of Rainforest Trees can be turned into Cocooned Trees by Spider Monkey through infecting them.
Sometimes, when hovering the mouse over a Rainforest Tree, the player can read "Peculiar Rainforest Tree" instead of the normal appellation, although the appearance is the same. This means it hides a peculiar item and can be investigated with a Magnifying Glass to discover it.
The Rainforest Tree is found in both the RainforestBiome and the Deep Rainforest Biome. When chopped, it yields up to 3 Logs, and there is a 50% chance that it will spawn Vipers. After three in-game days, there is also a chance for Scorpions to spawn from a chopped tree. While there is a chance to get no Vipers or Scorpions, a maximum of 1 to 2 Vipers or Scorpions can be spawned depending on the size of the Tree. If a normal or tall tree doesn't spawn any Vipers or Scorpions, it will drop an Egg. Like most trees, the player needs a Shovel to dig up the stump to obtain an extra Log.
During the Lush Season, the Rainforest tree blooms and drops a Jungle Burr when Strong Winds start to blow. The Jungle Burr can be planted to grow a new tree. Chopping down a blooming Rainforest tree will also drop one or two Jungle Burrs, depending on its stage.
There is a also a rotten version of the Rainforest Tree, named Sick Rainforest Tree, which can only be found in the Gas Rainforest Biome. Even if they don't share the same appearance, they yield the same resources. Sick Rainforest Trees do not bloom during the Lush Season. However, it is renewable if a Jungle Burr is planted in the Gas Rainforest Biome and is allowed to grow, resulting in the rotten version of the tree instead of the normal one.
The Cocooned Tree is a special type of Rainforest Tree, which spawns exclusively in the Deep Rainforest Biome.
Cocooned Trees serve as a nest for Spider Monkeys, similarly to Spider Dens. It is also surrounded by spider web that will slow the player (except Webber) when stepped on.
When chopped, it drops 1 log and 1 silk as a short tree, 2 logs and 2 silk as a normal (medium sized) tree, or 3 logs and 2 silk as a tall tree, meaning that you do not have to wait until the tree is fully grown to harvest the maximum amount of silk. However, the Den (as well as the spider web) will remain in place unless the stump is dug. Digging the stump will provide the player an additional log, but no additional silk.
Spider Monkeys are able to convert regular Rainforest Trees into cocooned ones by infecting them, making the Cocooned Trees renewable as regular Rainforest Trees are renewable through Jungle Burrs.
