The diary drawings mean that CJ has successfully built a shrink ray, which is what was used on you. You need the missing diary page from the trash can in the kitchen, and the diary key from the aquarium tank in order to see the diary. The other things you need are the thumb drive from under her bed (use the fan) and the secret message from the kitchen table (knock over the oil on the shelf, fill the cat bowl, then slide it to the table). The heavy grape will let you use the toaster to reach the top of the refrigerator, as you will later need the toy truck control. The telescope coordinates are on the bulletin board (87, 16) and the morse code book is on the bed.
Write with lemon juice on paper and shine LED light on the paper to see ther message!
