Well, no point wasting this golden opportunity! Casting some spells on your paws to help you grip, you braced yourself before scampering forward, climbing up Roxy's leg. As you climbed, you could tell that the material beneath you definitely wasn't skin, but wasn't quite metallic, either. Maybe it's protodermis? No, wait, that's a completely different thing... You'd have to figure out the answer later, as you arrived at the gap in Roxy's plating. Not wasting any time, you leapt in, brushing against the plate and causing it to creak—which caught the wolfess's attention.
"What the—!? ...Rrgh, can't believe this, I'm already getting loose paneling? ...Hrrmph, sure hope Freddy gets that grant soon, I'd love to go around without risking my wires showing."
With that, Roxy roughly shut the panel of her thigh closed, sealing you in with only the emergency lights to guide you. She hadn't even noticed you! And as a result, you now had full, undetected access to every part of the wolfess' animatronic body. Where would you be going first...?
