Doctor Bones

Doctor Bones is a rare mob that looks just like a Zombie, except it wears an Archaeologist's Hat. This enemy has 500 Health. Upon being killed, it will drop the Archaeologist's Hat. He may Spawn in the Jungle, above or underground, or on the surface at night, but he is more likely to spawn on a blood moon. The Archaeologist's Hat is the head piece to the Archaeologist's Outfit. Water candles have an effect on Doctor bones, increasing his spawn rate, allowing it easier for him to spawn.

Trivia

 * The mob's name is most likely a reference to Indiana Jones, who is often referred to as Doctor Jones.
 * Doctor Bones appears to Spawn more often during a Blood Moon. However, he can spawn during a normal night, too.
 * It appears that Doctor Bones will spawn after around 70-100 Zombies have been killed. This was tested during a Blood Moon and a total of 3 Doctor Bones appeared.
 * Doctor Bones, unlike other Zombies, doesn't jump up and down and appears to move like the players when Terraria was first released.
 * Occasionally, Terraria will show up in the taskbar as "Terraria: Doctor Bones and the Temple of Blood Moon", a reference to the film "Indiana Jones and the Temple of Doom".
