Minecraft wiki entry for Head, associated text: Skeleton, wither skeleton, zombie, and creeper heads are also always dropped by the respective mob if it dies due to a charged creeper's explosion. However, if multiple valid mobs are killed in one explosion, only one head drops. The one that drops a head is chosen at random. In Bedrock Edition, the number of head drops from a charged creeper explosion is not limited. If an ender dragon or the player is killed by a charged creeper, it does not drop its head.
