In Tockworth's Clockworks, Yuzzik and Slonk were the two prisoners left alive in Little Lockford's abandoned jail, having killed their cellmates for food and prison swag during the chaos of the Lockdown. When Ragnum Ironknuckles and Punmiri Tel-Phaeun discovered the pair while sheltering from a Clockwork Construct patrol, Yuzzik negotiated their temporary freedom through tense back-and-forth, securing release in exchange for cooperation against the threat posed by Tixie Taffebeser Tockworth. He and Slonk then helped clear the jammed turbine at Turbine Heights, restoring power to the city's grid; then, he helped the Adventurers subdue Tixie with well-placed shortbow shots, forcing her to retreat to her Overlook.
Yuzzik accepted ten gold pieces from Azimuth Andrea Almanac Caspian Kelshplotter to remain behind and hold the power station's turbines while the rest of the party figured out how to undermine the Overlook. As Tixie attempted to seize control of Little Lockford from the Security Center, Yuzzik repeatedly foiled her efforts from the turbines, buying the party crucial time to contact Igna Tynn Nimblepipe Bifimp Giltpurple Flint. They used the Apparatus of Igna to tunnel underneath the Overlook's iron shell and permanently destroyed Tixie, lifting the Lockdown.
Afterward, with the crisis ended and the promise of freedom fulfilled, Yuzzik and Slonk picked their moment. While the town celebrated, they ran off into the Deepways without so much as a goodbye to their liberators.
