Fusebox Code - 4312
There are two fuses in the elevator. When you get them, use your wings to fly up and get the other two fuses. Also, the key is in the lever. Pull the red lever and the gold key should pop out.
Icebox Code - 629
The icebox is in the Hotel Chill. If you look in the mirror you can see Cresil's shirt. It kind of looks like "g5a" but it's really "629". In the box you'll find the blueprints for the hockey stick.
Color Code - Yellow, Blue, Green.
Hope this helps.
