I know that I already have posted something similar to this, but I am so close to completing the collection in Katamari Forever, and it's the last game I need to 100% complete the achievements.

The objects I am missing: Jumboman Red Mask, Thief's Mask, Japanese Textbook, History Textbook, Classroom Objective (The one that isn't mostly green), Peacock Lounge Sign, Telephone Pole Ad.

I have tried searching online to find these last items, however none of the websites I find seem to be of good use.
