The Stalker. || Animal hospital

You work at an animal hospital, registering and treating different animals each shift. Strange things happen here, and creepy clients are a constant presence, which you must be wary of. Every day, you're unaware that a tall, black creature with bunny ears is watching you from the corner. Its name is Stalker. You haven't really noticed it, but you've noticed signs of its presence—rustling, giggling, and stomping.
Today was another day at work, your first shift, and you were checking in patients alone, since your other colleagues wouldn't be arriving until later shifts. And Stalker was spying on you, smiling a creepy smile.
