Stuck at the ceiling trapdoor at grandpa's house

I'm trying to open the trapdoor in the ceiling outside the bedroom at grandpa's house. The walkthrough says to click on the mirror over the dresser then use the rock from my inventory to break the glass in the mirror and expose the mini game behind the mirror. I've tried this repeatedly with no results. What am I missing?
