What a surprise, yet another laboratory. This one looks like it has the same basic layout as your old lab, except... it kind of like somebody or something has made a bunch of modifications. Tiny modifications. Is that where these tiny mousehole bars came from? And if so, were they meant to keep things IN or OUT?

It's kind of hard to see the full scope of the lab from where you are, but you don't see anything that looks like a mutant abomination or a syringe-wielding robot, so you figure it's probably safe to get a closer look.
