Mibbiwocket

Mibbiwocket is currently the oldest tortoise held in captivity. It was presented to King Healthorg, a gnome king of the late Fourth Age, by the famous explorer Admiral Bake, shortly after the creature's birth.

Mibbiwocket cannot be found in-game, but is said to be in the care of the Gnome Royal Family. More information regarding the tortoise can be found in the Varrock Museum.
