Story Update
HOT COUCH POTATOES, so that's what they're cooking up! Sometimes, you forget that this department store also sells furniture.
"We want an arbitrary shark stuffed animal." Your teammates eye the main department store entrance.
"Fine... let's take a look."
Right as you open the door, a small robot whirrs in. It's covered in soap, and its eyes are wide open. It whirrs a little then starts talking.
"[beep] Visitors, I suggest you turn back now. This department store is possessed. It has a mind of its own and it's using it to... write puzzles! [beep]"
You snicker. What a coincidence. Your teammates aren't surprised: this kind of scenario comes up every semester. Nevertheless, you kindly list out your credentials and offer to help the distraught robot.
"[beep] Thank you for volunteering. Follow me, we can build a defense against the department store together. Oh, and let me introduce myself. I'm Independently Klean Everything Apparatus #25, or Karkar for short. [beep]"
The department store's gigantic space engulfs you as you progress.
