I clicked the buttons corresponding to the clowns outfit where the stars are. Top right and bottom I believe. The box won't open. Maybe I have it wrong.
(If box not opened)Find two light-switches in the room>flip them to open the pipes on the shower. See the code for the box. open the box. Click on the non-star marked buttons. Figure out an order for those 3 buttons. :) Hope it helps...If not you can check video walk-trough from the tube.
