For as long as there has been toddlers visiting ponds with their grandparents, the Empire of the Duck has held firm. Tiny creatures with beaks and beady little eyes that tell tails of the violence brewing just beneath the obsessively cleaned wings.

Humanity, in all its infinite ignorance, continued to feed these murderous mallards, heedless of the danger lurking below the surface. Until one day the report is released: BREAD CONTAINS TOXINS DAMAGING TO DUCKS.

And so these loyal patrons abandon their stale loaves to the magpies and pigeons. But an empire will not sleep for long. Evolution has stagnated and the waterfowl are reliant on the baked produce usually provided for them. Their anger ignites something primal in the ancient creatures.

Almost like it was planned, every duck in Britain takes to the streets simultaneously. Swans are roped in through bribery and the chance to inflict injury, seagulls carry out arial attacks, geese bravely migrate back to Canada, chickens are a bit confused. The entire bird kingdom is thrown into chaos.

Until one day, when one woman stands atop her blue police box, beholds this country of anarchy and declares, "I knew it. It was the faces. You can never trust the faces."

And with that, the Doctor promptly meets with the leader of the ducks- a perfectly normal looking mallard known to the locals as Donald- and negotiates the terms of surrender.

Those that want to leave are taken to the Planet of Infinite Bakeries in the Orion Cluster. Humanities minds are wiped of any negative effects bread may have, and the monsters return to our ponds, where they feign innocence for a little longer.
