Tails had heard a loud "clang" somewhere in his workshop, and he was immediately on edge. After some critical thinking he dug up a shotgun from one of the tool closets, he wasn't taking any chances, doesn't mean he planned on using it though. He got closer to where he heard the sound, stopping before the dark room

Tails: "I- I know you're in th- there!!" He called, his voice shaky, "C- come out- or- or I'll shoot!!" He didn't sound all too confident however.
