One day in Zootopia, Judy Hopps and Nick Wilde were patrolling Savanna Central, and they were having a good run! They spotted/heard no signs of emergencies, no signs of speeders, and no signs of crime. Pretty peaceful, right?
WRONG. Suddenly, a giant space craft (NOT a flying saucer) was about to crash-land in the desert near the city. Judy and Nick went to the site of the crash and inspected the ship. The ship was definitely alien technology.
Soon after, the ship's cockpit opened, and out came some sort of lynx and a robot companion. The lynx was confused, and so was the robot companion.
"Where are we?" exclaimed the lynx. "And who are these lifeforms?!"
"Judging by these lifeforms' appearance and the city view," said the robot companion, "I would come to the conclusion that this is Zootopia, and these lifeforms are known as mammals named Judy Hopps and Nick Wilde."
Judy and Nick were shocked. "Who are you and how do you know our names?" asked Judy.
"True," said the lynx, "We haven't introduced ourselves. Ratchet the Lombax, at your service, and this is my robot companion, Clank."
"Hello," said Clank. "I have a database of every city and life form from all Time and Space."
"Hello, Ratchet and Clank," said Judy. "I'm a police officer, and this is my partner. By the way, DON'T call me a dumb bunny. I get really irritated when someone calls me that."
"I learned that lesson the hard way," said Nick.
"Yes, you did. Anyway, how did you get here, and why?"
"We'll answer both of these questions in a moment," said Ratchet. "But first, we need to get somewhere private. It isn't safe to talk here. Follow us."
"OK," said Judy and Nick.
