Are all the collectibles listed available to find if so are there any hints to find them? I have the College outfit, butter nut cafe tv show, and Luna's flash drive but can't seem to find any others. Am I missing something

Yes, you have got all collectibles except Wendy's shirt and Ghost Banger game. It's just same animations with slight changes made to them. You can watch it on the TV in the bedroom. To obtain it play Croydon House. Go to Tess's room and turn on her console. Interact with it and Ted will say he will buy it. After that quit the level and go back to your bedroom to watch it. It also depends on what ghosts you have caught.
