Is there a Minecraft mod with NPC players?

I'm looking for a Minecraft Mod with which I can record my movements and play them again. It is best to save the skin and be able to play several recordings at the same time. So several "fake players" should be visible at the same time.

I don't want to use the replay mod or the BlockBuster Mod because they are not compatible.

Check out Lekoopa unless that was one of the mods you don't want
