Wandering Monster

Anybody here know of a way to make random for wandering monsters? I haven't tried yet. I figured if somebody else has a method, it would be better to ask than experiment for 20 hours...

make some npc/monsters and when you go into a map make an event that puts them at a random place on the map. If you you want a mixed amount of them, you can do a random action for each monster and if you say 50% then the monster will be somewhere on the map 50% of the times you go to it.
