If you finding an seed with good variety of terrain in the nice biome like forest or grass landscape, then you choose the right seed. Spawn in the an grass landscape of small island, on the one side of seed lot of ice can be found but don’t worry because that is a small part of the seed. Otherwise you can find some couple of smaller island close the spawn island. Mostly of them is grass landscapes with beautiful beaches. Especially you will find two island has been covered in mostly sand and couple of grass blocks. Moreover if you go for, an extreme hill and majestic mountains can be found. Good Luck!!!!.
