A being named Grubbat Fhilch is being thrown to a sarlacc on Tatooine, and with his dying breath he curses Jabba for executing him and Boba Fett for bringing him to Jabba. We then watch as the sarlacc spits something out that preys like a parasite on several different creatures while it grows larger. Eventually we see that it is another sarlacc as it finds a new place to live. After some time passes Jabba is once again positioned above a sarlacc, the new one this time, with new victims: a certain young Jedi and his friends. It ends as we know the story by saying that Grubbat got his revenge in the end.
While it was an interesting story, I place this tale in with the Infinities stories. The events chronicled in this story conflict with pre-existing continuity, which means that I can't force it into the timeline anywhere.
