Best. Worst. Weekend. Ever.

When Comic-Con comes to town, three friends plan a surprise for the creator of their favorite comic. But the weekend gets off to a rocky start.

After their epic party ... er, "literary event" ... Zed, Treece and Hallie race to find a missing Argo before his dad realizes something's wrong.

The hunt for Tom Dunkins leads the Crash Crew to a pet store and a spooky "Blade of Dragons" maze. Patches breaks into Argo's house.

Patches grills Zed about his missing mushroom. A new scheme to sneak into Comic-Con forces Argo to confront his fear of performing in public.

As a special agent interrogates Zed about the hacker Digilord, Patches lures Treece to the hotel roof. Argo and Zed get stuck in a stinky predicament.

When the dumpster walls start closing in, Argo makes a confession to Zed. Later, the friends try to strike a deal with the mushroom's new owner.

While Argo deals with the fallout from the crash, Treece and Zed accidentally stumble into a LARPing event, and Hallie reveals a hidden talent.

With minutes to go before the colonel's return, a news alert gives the gang fresh inspiration -- and one last chance to make their dream come true.
