Pattertwig

Pattertwig was a talking squirrel who aided Caspian X in his fight against Miraz.

Like many others of the old Narnian animals, Pattertwig was much bigger and smarter than the dumb squirrels one would see on Earth. While he was a true Narnian, he was very chattery - just like all squirrels! As soon as he saw Prince Caspian, he accepted him as king and offered him a nut. The cheeky creature was sent to invite the other old Narnians to the Dancing Lawn and was then sent to Lantern Waste to see if he could find the aid that was promised to whomever blew upon Queen Susan's horn. Pattertwig was loyal to Narnia and a loyal subject of Prince Caspian.

Trivia
In the Prince Caspian film, Pattertwig was voiced by composer Harry Gregson-Williams.
