I came accros this seed after finding out about the Minecraft title secret.I didn't know why but i thaught "Marcus" so that became my Peaceful Map Seed

After looking around i found some cool - Not EPIC! Landscape fetures including Overhands, Mushroom Biome and Ravines

I do like this seed because what you can find is really good. I put it so that No structures spawn but if you set structres to spawn you may find some cool looking villages or somehting

If all goes to plan you should spawn in a large Jungle Biome and if your in creative spawn a Map and go down to eventully find the Mushroom Biome
