I had expected to find some other source of vibration that would make the fake barf fall from the ceiling but it hasn’t. The annoying music has been playing but it isn’t enough to make it fall. What else needs to be done to make the fake vomit fall down or at least a way for me to grab it or whatever.
Go back up to the bedroom where the stereo is. Look at the speaker on the left. You will be able to interact with this speaker. Knock it over and it will cause the fake barf to fall from the ceiling. You can now go down and collect the fake barf from the floor.
