It's a bit simple. Basically, I was editing the game when I found Mud x245 y16. So the code is saying where the mudokon is in the level. Oh and it has a cam code example R1P15C08. But you can't just change the position because you got to change the screen code you want it on as well.
In other words mudokons can be moved anywhere.
EDIT: Reply to crashpunk, the game crashes after the grenades explode when you're zapped. However, if you throw them 1 at a time you're okay.
