Rainforest: were lush, wet biomes with many trees, which had a 1 in 3 chance of being large trees, instead of 1 in 10 like all other biomes. They were similar to forests but had a large amount of tall grass and ferns and lush green grass due to temperature and rainfall requirements.

Shrubland: are largely identical to the savanna biome, featuring few trees and no tall grass.
