Globby was a young male stoat member of the Sable Quean's Ravagers, serving under the team leader Daclaw. He was disobedient, impudent, and greedy; he caused Daclaw a lot of exasperation with his insolence.
Globby and his friend Dinko were sent to spy on Redwall Abbey and determine if there was any way to take hostages from within the structure. Defying Daclaw's orders to remain outside the Abbey, Globby gained entrance to Redwall by climbing a nearby tree and jumping onto the walltops. After a long search, he found the Kitchen, where he ate everything in sight, making a thorough mess of the place before falling asleep in the middle of the wreckage.
In the morning, Globby was captured by the Redwallers, who caught him while he was still asleep. He was sentenced to clean up the kitchens by Abbess Marjoram and Friar Soogum. Soogum later tied him to a table leg to prevent him escaping, but the old watervole forgot to clean the table of silverware, and Globby used a sharp knife to free himself.
After the two Dibbuns Tassy and Guffy went missing, the Redwallers began searching for Globby to question him. Thinking they meant to harm him, Globby armed himself with the kitchen knife and sneaked off to the Abbey attics, only to be discovered by Bribby and pursued by Abbess Marjoram and several others.
Globby locked himself in an upper room; despite the Abbess' insistence that he was in no danger, he refused to come out of his hiding place, threatening to kill anyone who followed. In an effort to coax the stoat out, Brother Tollum tried to swing in through the attic windows, but he collided with Globby and was killed by the knife. Globby suffered a severe injury right below the throat in the collision and died shortly thereafter. Right before he died, Majoram asked him if he knew anything about "Corim Althier"; his reply, and his last words, were "Althier, Althier, Sable Quean!"
