A small village with a blacksmith, chest and a ravine closeby from which you access the cave with the mob spawner.
Walk straight ahead at spawn to get to the little village. In the village is a blacksmith, enter it to get the things from the chest. When we tried it out we were lucky enough to get some iron gear, apples and gold.
On the right side of where you came from to the village there is a ravine and that’s the entrance to the tunnel which ultimately takes you to the mob spawner.
