This is Jake's private journal.

One day when you were feeling especially frisky, you swiped it with your APPEARIFIER, not actually expecting it to work. But then you debated with yourself for weeks over whether to read it. When you finally took a peek, you were strangely relieved to find all this nonsense, instead of his private thoughts. But you still didn't have it in you to cop to the theft. You just agreed what a shame it was about his missing book.

You have no idea what these letters mean. Some kind of code? BARK? KRAB? ABRAKABABRA??? You have no clue what was running through that kid's head. Not unlike always.
