Depending on which direction this takes, It could possibly become a srs SCP.
Now, you may be thinking "What the fuck?", but it is an interesting idea. Say, a regular old-school skeleton that stands right next to the entrance to the class room, that tries to finger girls on the way into the classroom. Nothing "MEG4KET3R" here. Perfectly safe.
I have an interesting hook, I thought it would be fun to experiment with.
