I am stuck on the phone in the bedroom. The old dialing system. I am assuming..

For the phone, you go into the bathroom, use the wrench to turn on the water in the sink and the steam puts a number on the mirror. I believe the wrench was found in the room with the sawdust.

You need the container of vasoline from the bathroom which allows you to free the wrench using the crank. Get the wrench and take the crank back. The crank you'll use again on the jack-in-the-box. It'll pop up. Take the tape of the left eye. This tape allows you to fix the phone. The phone number is obtained by using the wrench on the hot faucet which will create steam, etc etc. You open the attic using the umbrella found in the tree house which becomes accessible when you light the saw-dust using the match from the puzzle box found under the floor board found in the room where you rearranged the books using the name "fortuna". You also need the blower thing found under the bed in the kid's room. Obviously this question is a year old at this point, but you know, for anyone else who's wondering.
