hey i'd like to know what mobs come from spawners on the 360 edition and does it differ from PC version
also why are there pig spawners but not sheep or chicken spawners as well ?

There are no pig spawners. The earlier versions used an image of a pig inside all spawners even though they spawned spiders, skeletons, etc., so occasionally a glitch will show up where the image inside the spawner reverts to that of a pig. If you save and exit the game and then reload the world, the image will probably correct itself and display the proper mob for that spawner.

Mobs spawners that currently exist in MC360 are: Skeletons, Spiders, Zombies, Cave Spiders, Silverfish, and Blazes. I believe this is still the same as the PC, but I'm not certain. They may have additional mobs now that use spawners.

thanks
