Behavior
Whenever a player approaches a newly-spawned Skeleton Horseman, it transforms into the Four Skeleton Horsemen and starts charging at the player. The Skeleton Horsemen also have high hit points and require constant damage to be defeated. They sometimes shoot at the player with a Longbow, dealing extreme damage.

Trivia

 * Rarely during Ancient Hunts, a single or less than 4 skeleton horsemen can spawn. They are also seen without a boss health bar.
 * An individual Skeleton Horseman can also be found in a secret area in the Dingy Jungle. This one has a boss bar however.
 * Individual Skeleton Horsemen have the lowest health of any mini boss in Minecraft Dungeons, but when combined have as much health as an Evoker.
 * In Default difficulty, the Skeleton Horseman is the rarest miniboss in the game, only spawning in the fossil area in the Cacti Canyon.
 * The first skeleton horse players find has a rider, unlike in the base game.
 * It's very rare to find this miniboss going solo.
 * Before 1.8.0.0, the Skeleton Horseman's boss bar would show one boss bar that only showed the current health of the nearest horseman and would change if the player attacked another horseman.
