Plue is a Silver Key Celestial Spirit with no actual combat abilities, stated to be usually kept as a pet for less powerful Mages, including Lucy herself as his owner. His key was sold for 20,000 Jewel.

Profile and Stats
Name: Plue

Physical Appearance
Plue is a short and stout white creature with bland eyes and a golden horn-like nose reminiscent of a carrot, giving him a slight appearance of a snowman. His body is often shaking nervously, though this doesn't always occur. He cannot speak besides saying "puu-puun", although Natsu seems to be able to understand him anyway. He mostly communicates by using gestures and motions which Lucy finds adorable.

Personality
Because he is not made for combat, Plue serves as a cute companion instead. He is very obedient and ready to help Lucy whenever she needs his help. Along with that, he enjoys sweets and shares a close friendship with Happy and is often seen teasing Lucy and Loke along with him. He is also very apologetic, as he immediately apologized to his owner after harming her under the influence of Sherry's Magic.

Powers and Abilities
Enhanced Speed: Plue is shown to have enough speed to catch up to Lucy while they were running from a mysterious figure, as well as to dance faster than one of Daphne's Lizardmen.

Immortality: As a Celestial Spirit, Plue cannot die, unless he is somehow forced to stay in the Human World.
