Is there a way to increase spawnrate in the "Minetest" Game? I have downloaded a few mob mods (all from tenplus1) but after play for about 3 hours i just saw a penguin and a creepy sand monster. I Want to make a good surivival modpack but if don't have mobs is just worse to play.  


(I tried the game Voxelgarden and is very cool but i'm having trouble with LAN multiplayer. In the minetest standard game i dont have these trouble. And sorry for my bad english)
