Dib summoned the Shadowhog via Spelldrive to test his powers on Gaz, which made everything but actual pork products taste "like a pig." After receiving some help from the Swollen Eyeball Network (only after being threatened by his sister), Dib was able to pull them both into the Shadowhog's dimension.
The Shadowhog had Gaz go through two trials, both of which she handled with ease, thus freeing her from his curse.
Despite planning to send both children home free, the Shadowhog sentenced Dib to cleaning his toilet with a brush attached to his head, due to Dib begging him to "punish (him) instead."
The Shadowhog and Gaz seem to get along very well: They were shown playing video games together, and the Shadowhog later bought her ice cream and danced ballet for her while Dib was getting attacked by giant pig guards outside. The Shadowhog and Gaz were later shown having tea together, and Gaz even confided to him her troubles concerning Dib's constant ranting over Zim, before she was interrupted by the arrival of Dib.
