In Monkey Quest, checkpoints are things that save your location if you die, so you'll teleport back to the checkpoint you activated if you where to die. To activate them, simply just walk by them.
Once a checkpoint is activated, fireworks will shoot out and a sign with a checkmark on it will come out.
