A weird hissing escapes your lips and you feel the floor shifting, you jump back just in time as the sink seems to be expanding and replacing the tiles below, leaving a massive gaping tunnel at the middle. It almost looks like a water slide, but with a 50/50 chance of you perishing at the bottom.
Well, it is now or never. And if it's not now, then it's a forever never for Ginny.
You take a step towards it, and slide down to the Chamber of Secrets.
