Basil and Ratigan hung back with the boxes while Captain Leela and the rest of the crew spoke with the aliens, finalizing the delivery and collecting payment. The aliens had the look of studious camels, but with ten fingers on each hand and tentacled lower halves which they slithered about for locomotion.

The two had purposefully unloaded the boxes under the shadow of the far side of the ship.

"Ready, Basil?" Ratigan asked.

Basil waited until Captain Leela and the lead alien were shaking hands. "Alright, now."

Their hands darted among the boxes, unlatching and upending them. Scores of rats and mice scurried out, weaving through the grass before disappearing into tall bushes. Once all the boxes were empty, Basil and Ratigan straightened their coats and moved away, rejoining the rest of the crew.

"Thanks again for choosing Planet Express for your delivery needs," Captain Leela said.

"Indeed, mm. Take us now to the mm, boxes, so that we mmight place them in our mm, facility, yes," the alien at the front of the group said. The others all murmured and nodded in agreement.

"Right this way." Basil and Ratigan prepared their excuses and reasonable explanations, following from the back. But when they all rounded the corner, their well-thought-out alibis went slack with their jaws.

In the bushes where the rodents had disappeared was suddenly the beginnings of a primitive society, buildings constructed out of branches and leaves.

"Oh no!" cried the lead alien. "The mm, hyper-intelligent rodentia have mm, escaped!"

"The what now?" Bender asked.

"The hyper-intelligent rodents that we mm, developed on Nim-7, before we had to abandon that mm, planet due to their mm, previous escape, yes."

"These rats sure seem to escape a lot," Fry commented.

"We mmust all evacuate immediately, yes, before they—" The rest of his sentence was cutoff after he was shot through the head by a very small gun. In the moments they had taken their eyes off of the rodents again, their society had advanced several stages, and they had organized themselves into an army.

"Death to the camels!" yelled one large rat, leading the charge. The camel-aliens turned and fled, the rodents bearing down after them. In the distance towards the city, chaos erupted, multiple spaceships taking off as some of the buildings exploded and burst into flames.

"Excuse me sires," a small voice squeaked, and Ratigan and Basil looked down at the mouse at their feet. The mouse read from a scroll: "We recall the kindness you showed us in enabling our escape. Statues shall be raised in your honor, and you and your companions are granted safe exit from our new planet." It bowed to them. "I must go now, and you all should be going too. We have much to do to make this planet civilized for rat and mouse-kind." With that the mouse scampered off.

"Wow, usually it takes at least another 10 minutes before our deliveries go wrong this badly," Fry said. Another explosion sounded in the distance.

"Welp, we already got paid and this planet is done for, so unless we all want to get caught in the crossfire, I say we vamoose," Bender said.

Basil and Ratigan were silent as they sat on the ship.

"You know, I really didn't think—" Ratigan began.

"Not. A word," Basil bit out.
