What Happens If A Skeleton Kills A Charged Creeper?

When a creeper is killed, it has a chance of releasing between 0 and 2 gunpowder depending on how much times it was hit. A creeper head will be dropped by the creeper that was killed by the explosion if it was a charged creeper that caused the death. If a skeleton uses an arrow to kill a creeper, the creeper will leave behind a music disc after it dies.
