Two officers enter the recreation center of their spaceship. It’s full of animals.
Officer 1: Everyone in the rec room has turned into an animal!
Officer 2: It’s that alien virus we picked up. It mutated their DNA!
The two officers find a rabbit sitting on a blue necklace.
Officer 1: This is the captain’s! Captain Walker, can you understand me?
Officer 2: Somehow the DNA mutation not only changed her cell replication, but transformed her existing body mass.
In the doorway, the grumpy captain stands next to a lieutenant, looking over the two terrified officers holding the animals, who appear shocked to see them.
Captain: Lieutenant, you told me a petting zoo would raise morale.
Lieutenant: Sorry, Captain.
