The seed I'm talking about is: Tetris
(This is written WITH a capital T)
In this world you spawn in a snow biome which is next to a dessert biome with a Dessert Temple which contains 1 diamond, some iron, gold and more! in that same dessert there is a ravine inside a hill, in that ravine is another ravine and in that ravine is ANOTHER RAVINE which contains a cave system which contains 9 diamonds. Next to the snow biome is also a Jungle Biome, and there are a lot of lava puddles close to the spawn.
I hope you like the seed and if you do please leave your findings
