Master Prune

Master Prune (Korean: 사부 건자두, sabu gonjadu) is an Epic Pet that was released alongside its owner,, in the first half of the Mighty Duo update. It occasionally fires a blast of energy that destroys all obstacles in its path. It also rewards points simply for firing the blast, not reliant on how many obstacles are destroyed.

Story
''The venerable master of Plum Cookie. A stalwart defender of Cookies and the first teacher of martial arts in the Cookie World, Master Prune's skills are legendary. Don't let the dehydration, age, and wrinkles fool you, there's still much to learn from this wise sage.''

Trivia

 * Master Prune's skill used to refer to its beard as a "mustache", even though it is referred as a beard in the Korean version of the game at the time. It's unclear why this translation change was made.
 * This oddity can also be seen in one of the Cheer Squads, Mustached Trio.
 * Master Prune is the first instance of a Pet clearly having at least some leverage over the Cookie it is connected with, in this case being Plum Cookie's (as well as 's) teacher of martial arts.
 * Master Prune's internal name is "pet0139".
