Herbert is the skilling pet obtainable from Herblore. He is unlocked by inspecting the Herbert pet.
Herbert is unlocked by training Herblore via making potions, cleaning herbs, or burning herbs. It can also be unlocked by mixing tinctures at the Apothecary in the Dream of Iaia. Gaining this pet is based on the amount of experience awarded at once; the more experience granted per item made, the greater the chance of gaining this pet. The chance is not affected by experience boosters.
Unlike many other followers, Herbert moves at a walking pace even when their owner is running, likely because tortoises are generally regarded as relatively slow animals.
