Molemum Burbee was a kindly old female mole resident of Redwall Abbey. She was the aunt of Foremole Grudd Longtunnel and close friends with Abbess Lycian; the two would have tea together on the western parapet of the Abbey's outer walltop every morning, noon, and night. Burbee was gentle in nature and practical in her advice. She used sound mole logic to try and help Tiria Wildlough, Brinty, Girry, Tribsy, Old Quelt, and Sister Snowdrop solve the riddles and rhymes of the Geminya Tome.
In Lycian's letter to Tiria on Green Isle, the Abbess wrote that it was Burbee who quietly informed her that Tribsy was to be made Foremole following Grudd Longtunnel's retirement.
