Trouble with finding collectibles (Psychonauts 2)

Issue:

I'm struggling to find the last few figments or other collectible items in the game. Heeeeelp!

Check the Internal Manual to find maps of all areas of the game with helpful information about collectibles in each area. This might help you narrow down your search!
Some collectibles can be sneaky and quite well-hidden. Even if you looked quite well, you might still be missing something... good luck!
If you return to a level after completing it to look for figments you missed first time around you might find some areas are no longer accessible for story reasons. But don't worry, figments from those areas have been relocated to a nearby accessible area. Figments can always be collected after you complete a level.
