You must be a baby to do this i think but anyway first get the strange rubber object from the drawer in daddy's room then go into the baby's cupboard, step out of the cupboard and look outside the window if it is looking not like it did originally then you are doing it correctly, then go outside to the big rock in the back garden and start whacking it with the strange rubber object, the rock should break into pieces (you can eat the pieces it doesn't do any harm) then go through the hole and you should get the control room achievement, inside the control room you should see a terminal with all manor of weird things you can do, never mind that though there is a door to the left of the terminal with a button next to it, press the button and daddy will walk up to the door, get scared but then starts laughing and then you will get tazed to death and also get the achievement!
