Lately I've been getting nothing but forest island worlds, but I figured someone might want one of the seeds for it so here it is. You spawn on a forest island with some pigs and chickens, and sugar cane on it, and there's also a sunflower plains biome on the island. In addition, there's a pond with a gravel beach around it. Surrounding the island are two variants of the ocean biome: the traditional ocean and the deep ocean version (east side of island). To the northeast of the island is a tiny plains biome island.
The seed works with all default, large biomes and amplified world types, though it's interesting to note that, on large biomes, you spawn on the tiny (well, on large biomes, it's rather big) plains island, instead of the huge initial island.
Hope you enjoy!
