Timing random stuff

ok - i did that and now they all come seperatly but they dont stay on the stage, how would i get them to stay on the stage.

Also, it does to many, i only want it to do the function a certain amount of times and in order to do this i put it in a for loop like this:

for (i=0; i<5; i++) {
	setInterval(printC, i+100);
}

But it doesn’t work, it happens more than 5 times.

How would i fix these two things - thanks
