Baby Skeletron Head

The Baby Skeletron Head is a pet summoned by the Bone Key, which is dropped by the Dungeon Guardian. It is difficult to obtain, due to the absurdity of the requirements and skill needed to kill the Dungeon Guardian. Despite the difficulty of obtaining this pet, it does nothing.

Bugs

 * Will sometimes spawn 2 Baby Skeletron Heads when entering a world.
 * When teleporting away using a Magic Mirror, the head will not teleport with you causing it to fly back to you.
 * This is the hardest pet to get as of the most recent update it's still great to have because it's a symbol that you've beaten the dungeon guardian.
