A brand new, extra long issue of Invader ZIM - now released quarterly! Tasked with a very important mission, ZIM's robot servant, GIR, ventures into the wide world to assist his master with his most diabolical scheme yet! But no one counted on GIR's distractibility... or time travelers... or weird hybrid lab animals who need rescuing. All in a day's work for GIR! But what was he actually supposed to be doing, again?
