When the games starts you find yourself in the middle of a flower forest. If you explore (close) around the hilly area you’ll find a cave entrance (see photos). Descending into the cave there’s a lot to explore. You’ll likely come across spiders from a dungeon/monster room that has a mob spawner in it.
This may be the best Minecraft PE seed for finding a mob spawner. Boy is it close by. When the game generates the map and landscape from this seed you’ll spawn on an oceanside hill. Dig straight down and you’ll fall into a shallow cave with a zombie mob spawner in it (some call these dungeons… some monster rooms…) after digging only one or two blocks. Check out the chest by the mob spawner. When we smashed it we found an iron ingot, some gunpowder, bread and some wheat.
Diamonds under spawn is what you’ll get from this Minecraft 0.9.0 Infinite seed. Digging straight down you’ll find lapis lazuli, iron and coal, too. Careful, there are skeletons protecting the diamonds. To make sure you find the diamonds and emeralds be sure to dig out 2 blocks around any ore that you come across.
