Next second, the sink began to move. The sink, in fact, sank, right out of sight, leaving a large pipe exposed, a pipe wide enough for a man to slide into.
There is no content to collect.
This moment has 2 zoom levels.
Nothing to do.
Click on the left-hand tap on the right-hand sink. The tap will start spinning faster and faster and then it will light up and then a chunk of brickwork moves inward and down, revealing the entrance.
You can hear wind howling somewhere. Once the entrance has been opened you can also hear gloopy noises from the slime coating the pipe down to the Chamber.
