The comic's first major arc, focusing on Grampa and Julie's search for Stephen, the largest shark in the world, and later their quest to reunite him with his mother, were spread across the magazine's issues from October 1999 to March 2003. After every few episodes, the strip would take a break from the magazine for several months before eventually resuming the storyline. Klasky Csupo produced a pilot for a Grampa and Julie animated series in 2006, but it was not picked up for a series.
