i have tried 5 different things and it wont stop change icon states(4frames worth of time),dissapere and announce it's final X,Y coordinates so take a look at this and tell me what might work better...

mob
cow
icon = 'cow.dmi'
icon_state = "walking"
New()
..()
LCycle1()

mob
proc
LCycle1()
if(client)
return
step_rand(src)
spawn(7)
world << "[src] is at '[x], [y]!'"
spawn(7) LCycle1()
