Colossal Tree Forest Biome

Forest biome full of giant trees (~150 blocks tall, maybe 20-40 block diameter, with roots).

in the forest, the dirt floor is made of podzol and rooted dirt around the giant trees.

the trees are made of a special sappy wood which won't catch on fire.

Diamonds are more common under giant trees.

the trees have sap veins, which can be smelted into sugar.

ruined structures and villages would be found around roots, and in the branches. entrances would be
carved into the trees which lead to underground mansions.

Underground would always be lush caves biome.

Spiders would spawn more frequently.

Silver Fish would infest blocks in the first layers of the surface dirt.

Animals that drop food would not spawn. you would have to find other structure to find food, or eat apples.
