I have every ending and the tooth is gold, but the achievement won't unlock ): Am I missing something obvious?

Has anyone else seen this? I don't know what conditions have to be met, but sometimes if you walk into the painting across from the entry to the TV room, you pass through and there's a stage with lights and a group of simple, worm-like things playing a show. No idea what they're for....
