Hey, So i got the idea that, is it possible to have a "Button" or something hooked up to red stone that will spawn a mob near by, May it be any friendly or aggressive.. Thanks
You should check out Creaturebox, it lets you configure spawners to activate with redstone. You can set what spawns, what requirements it needs to spawn (correct light, grass, and/or whether a player needs to be nearby) how many spawn, how large the limit of mobs is, etc. It's quite a nice plugin and looks like it's what ya need
