Ruro
Ruro was an anthropomorphic squirrel in the book Lord Brocktree from the Redwall series by Brian Jacques.
Ruro was a female squirrel and part of Jukka the Sling's squirrel tribe. When Fleetscut asked for aid in Lord Stonepaw's battle against the usurping Wildcat, Ungatt Trunn, Ruro was the most receptive of his plea.
Ruro journeyed with Jukka, Fleetscut, and the squirrel tribe to the court of King Bucko, where the group met up with Lord Brocktree and his companions. Together, they raised an army and launched an assault upon the mountain of Salamandastron, which was at that time occupied by Ungatt Trunn, Lord Stonepaw having died some time earlier.
When Jukka was slain in the catacombs beneath the mountain, Ruro succeeded her as leader of the tribe.
