I was flying around my island and found a Mesa biome. According to the Wiki, it's the second rarest biome in the game. There weren't any islands spawned in it. I just found this interesting.
I wonder what grass block will look like there. It turns kind of yellow in a desert biome, for example.
Mooshroom island is the best biome for me. It has the greenest grass in the game. I'm in an ocean though :<
I'm in plains, swamp and ocean Swamp is amazing it's got almost blue grass EDIT: I lie it's not ocean I can't remember what it is
I did a trade today in a mushroom island biome. It is the rarest in the game. Grass is greenest there. According to the Wiki, mushrooms can grow there at any light level. In a normal game, hostile mobs don't spawn on a mushroom island. The owner of the island has no idea how rare it is.
