on that spider spawner there is no dungeon on that coords. but the zombies spawners 1 and 2 never tried it yet and a skeleton ones, but in my world, same seed! i found a zombies just in front of the pyramid temple close to the village: coords x 73 y 63 z -149,,and for the skellies x 35 y 40 z -330.
After continued searching on the Internet, I came across a seed that is ALMOST exactly what I want. Credit goes to slate79 for this awesome seed. I just wish the Mesa was bigger. The seed is:
"-303721893827871" (without the quotes, but with the minus sign).
This seed has all wood types, Swamp, a Mesa or Mesa Bryce (this is one of those seeds that changes if you create it again), 3 villages, ALL temples (Desert Temple, Jungle Temple, & Ocean Monument), a nice sized flower forest. Found a single pumpkin growing in one of the Jungles, & melons somewhere else.
Haven't checked out the seed from Delvin4519, but this one is pretty nice. Wish the Mesa was a little bigger, or less cut off by water. Also has a mostly underground ravine in the Mesa, which is great because there's a Zombie spawner down there, but it means less hardened clay. Still, an amazing seed.
The strong hold is located at the water edge, below the village by the mesa, there is a cave that you can take to it X170 Y39 Z144
I love the map, I have not found any diamonds or a mine shaft yet
I started this seed..and love it..decided to make my home base under the clay mountain/towers, easy to find and see from distance, local to many things. I am sure down the road i will make my castle elsewhere...but for starting off..its a good place...i chose it also because if i go hide in a village..the zombies at night come out and sometimes kill off the villagers...so best i stay away from villages at night until i get enough stuff to surround by fence and tons of torches
