Decapodian invasion of Earth

The Decapodian Invasion of Earth started when Dr. Zoidberg ate the Earth Flag on Freedom Day and was sentenced to death, after refusing to apologise. He hid in the Decapodian Embassy which was soon invaded by the DOOP Army, however, since the embassy was technically on Decapodian mud this was an act of war, regardless of this Zapp Brannigan called their bluff, thus causing a war between Earth and Decapod 10.

The Decapodian Warships attacked all ships in Earth's skies. The Nimbus began an attack on the ships but the missile codes were stolen by the Decapodians, since Zapp stupidly chose to hand the key over to a obvious Decapodian spy making the Nimbus' weapons useless. The Nimbus was cut in half, and with their weapons useless the human race had to surrender, and was subsequently enslaved. After the crew of Planet Express decided to fight back, Fry came up with an idea to steal an ancient heat seeking missile and attack the Decapodians.

The Decapodians revealed the Mobile Oppression Palace, constructed by the slaves and used to maintain their control on Earth, and after sending the Decapodian warships away, the Mobile Oppression Place began to destroy the city. Fry deployed the missile but it missed the MOP as all Decapodian technology is cold blooded. After Zoidberg's lawyer was killed in his honor, Zoidberg set fire to the Earth Flag and threw it at the MOP, causing the missile to sense, hit and destroy it. Because the Decapodians had been relying solely on the MOP to control Earth, they surrendered, and the Earth was liberated, with Zoidberg honoured a hero.
