Tragglo Spearback was a male hedgehog member of the Waterhogs. He was the eldest son of the seven children of Rufftip and Gurgan Spearback, the grandfather of Drogg Spearback, and the great-great-grandfather of Sister Floburt and Brother Egburt. Tragglo succeeded his father as leader of the Waterhog tribe, and later relocated to Redwall Abbey and became one of its Cellarmasters.
He often led a gang of Dibbuns around teasing Florian Dugglewoof Wilffachop. Tragglo was wounded in the first battle between the Redwallers and the Marlfoxes by a piece of metal from a slingshot.
