Each collectible is part of a set. Find all of the collectibles in a set, and you can turn them in to various NPCs as special requests for points if you unlock those NPCs in the story. All of these points go toward the character level for whichever character you’re using when you find them or turn them in.
Burne (3 Headlines): 50pts. Irma (5 Diaries): 75pts. Punk Frogs (8 Disgusting Bugs): 100pts. Vernon (5 VHS Tapes): 100pts. Dimension X (3 Crystals): 200pts.
Alongside defeating enemies and completing level challenges, turning these in is a good way to get all characters to Level 10 for the No Need for Mutagen! trophy/achievement. A single playthrough on Chill difficulty only takes about three hours, and you can fully level one character and get another roughly halfway. You can carry character progress over when starting a new story playthrough while resetting all of the levels and secrets.
Finally, getting all secret collectibles will give you the Biggest Fan! and Multitasker trophies/achievements for finding all cameos and completing all special requests.
