Uggo Wiltud was a plump young hedgehog of Redwall Abbey, and probably a distant relation of Pinny, Twoggs, and Drogbuk Wiltud. He was a bit of a glutton, like all the Wiltuds, and could not swim. Uggo got into serious trouble with Abbot Thibb when he stole a huge marchpane-covered fruitcake and ate the entire thing himself; he was sentenced to kitchen labor for three days. While he was still suffering from a stomachache after gorging the cake, Uggo had a vision of Razzid Wearat and the crew of the Greenshroud coming to attack the Abbey. Relieving Uggo of his kitchen duties, Jum Gurdy the Cellardog took the young hedgehog with him on a quest to seek out Wullow, an old otter who reportedly knew something about Wearats.
