Rollo was a male bankvole of Redwall Abbey and the son of Lettie, who was murdered by Slagar's gang. As a Dibbun, he was quite mischievous and tended to get into trouble frequently. In his youth, he worked in the Abbey wine cellars. He idolized Basil Stag Hare and Ambrose Spike, and was often scolded by his mother for repeating the songs they sang.
Rollo was useful to the Redwallers when solving the riddle Martin the Warrior spoke to Abbot Mordalfus. The solution to the riddle would help Matthias, Basil, Jess Squirrel, and Orlando the Axe complete their quest to find the Abbey's missing young ones. Rollo found Redwall's foundation stone, the tomb of Abbess Germaine, and the other riddle that was inside the book her statue was holding. Rollo, Cornflower Fieldmouse, and Mrs. Churchmouse solved that riddle, which led to the bird statues on Redwall Abbey's roof, which had writing on them. Queen Warbeak copied it by doing a "rubbing" and with some of her sparrows delivered it to Matthias and company.
At one point, he was captured by General Ironbeak and held hostage in Redwall's bell tower. He was rescued by other Redwallers.
As an adult, Rollo became the head Recorder of Redwall. He wore spectacles and was fairly learned and intelligent, but not without a sense of humor. He was of great assistance to Tansy, Craklyn, and Piknim in their search for the Tears of all Oceans. He ordered the burning of St. Ninian's after Piknim was murdered by jackdaws who were residing in it.
