Skeleton Creepers will simply follow anything that attacks them , but when in a 5-block radii they will try to explode. You have one second to run away, as the Skeleton Creeper will deactivate its timer and continue tochase you. They are a bit sneaky like Skeletons. They will drop 0-2 Bones or Bonemeal and Gunpowder or TNT when killed.
