After being thrown in jail, Dr. Zarkon activates another monster, this time a pigeon the size of a 747. Meanwhile, Gizmo and Wheels are flying to Blatvaria, the home of Hector Von Gloom, alias Dr. Gloom, when the sad Dr. attacks their plane.; The giant pigeon flies to New York and news of an airliner being hijacked to Blatvaria travels quick. Red then splits the team: he, Spike and Squint will journey to Blatvaria to rescue Wheels and Gizmo, while Nitro and Angel deal with the monster pigeon.; Angel gives Nitro an idea for dealing with the giant pigeon, while Spike defeats one of Gloom's robots. Then Red, Squint and Spike find Gizmo and Wheels in Dr. Gloom's torture chamber.; In Gloom's torture chamber, he subjects the team to worst thing of all: the panned flute maestro Blanfir. He then lets the Explorers' go free. Meanwhile Nitro and Angel set up a large pigeon balloon from the last Thanksgiving's Day Parade that decoys the monster pigeon. The decoy and the smitten monster then travel to Blatvaria, where Nitro programmed a computer to take the 2 giants.
