When a monster is killed, it will drop 200 yggs around it with a cell 10x10.

You should've said that before. Using Mumbles' code as base:

 

-	script free_yggs -1,{OnNPCKillEvent:	if (killedrid == 1002) { // Poring Mob ID is 1002		getmapxy(.@map$, .@x, .@y, 3);		for (.@i = 0; .@i < 200; .@i++) { // Up to 200 Yggdrasil berries			makeitem Yggdrasilberry, 1, .@map$, .@x + rand(-10, 10), .@y + rand(-10, 10);		}	}	end;}

What if a specific monster? Poring to be exact.
