Description
CliffTree now supports 1.21.1 and 1.21.9+
CliffTree
Cliff under a Tree, or CliffTree for short, is a world generation datapack that adds new biomes to the Overworld and bringing a fresh touch to some existing ones, all while maintaining the spirit of vanilla.
This is probably obvious, but the name comes from the lyrics of Adventure Time's ending theme. I just really like the show.

New add-on: ButterBee
ButterBee spices up CliffTree's ecosystems by adding new biome-dependant variants for chickens, cows, pigs, wolves, and even one new frog! This add-on will hopefully make exploration feel fresh, as you might discover new faces along your journey!

Features
New biomes and variations
From the searing Shrublands to the chilly Bog, CliffTree adds various new biomes to explore in the Overworld. See all new sights like the Oasis or the Tundra, or a variation of a familiar biome like the Snowy Old Growth Taiga or Sparse Forests!
New rivers, water colors, and deeper oceans
This pack tweaks almost every biome to have new water colors, as well as new river biomes to match, and deeper oceans to explore. The distribution of sand, clay, and gravel underwater are also altered to provide a nice and cohesive gradient instead of being random disks.
Cave biomes
CliffTree makes a big change to how caves work, surface biomes no longer extend all the way down to the underground, and instead taking their place are several cave biomes. Some are more generic caves, while others are more interesting to explore like the icy Frozen Caves, terracotta-filled Warm Caves, or the scorching depths of the Inferno!
A touchup of existing biomes
There are also many small tweaks to the existing biomes, such as their distribution, or direct visual changes like terracotta on the sides of Savanna Plateaus, fallen logs on various forest biomes, more stone on the sides of cliffs, and wide Beaches reminiscent of their beta looks!
New tree shapes and foliage rules
Foliage like grasses and flowers can now be planted on sand and snow blocks! Some trees have also received a makeover, like Birch and Small Jungle trees. Saplings also have custom growth rules, with only some saplings being able to grow up on sand and snow, and certain blocks allowing the growth of rare tree types like Jungle Bushes and Swamp Oaks!
