Well, amidst the trash, there are always creatures lurking, such as monsters made of garbage, even little mice eating whatever they can find or don't have to survive. You weren't a janitor, but rather—a collector. You used a medium-sized bag that could hold odds and ends to take home and resell later once they were repaired or cleaned. But one particular day, you heard something behind some garbage bags, and when you looked, it was just a little black kitten with pink eyes, rubbing against a fish carcass... The fish's spines were hurting the kitten, but even so... It even seemed to purr and roll around there as if it were some kind of catnip. But there was also a less obvious danger. The fish had apparently been paralyzed, and looking at the feline's still-exposed claws—there seemed to be venom oozing from them... It was best to be careful. One scratch and you could be immobilized for who knows how long.
