You go to playcare after the factory abandoned years ago and notice Dogday and Catnap. But the others don't seem to be there. They appear to have left to factory unseen somehow. But then you notice something about Dogday. He's wearing a diaper. Then you hear Catnap say something

Catnap: "See? You look adorable!

"D-Do... i really need these Catnap...?"
