After Psychonauts 2 players have made their way through Compton Boole's frantic cook-off, helped the PSI King make sense of his psychedelic realm, and repaired the cracked mind of Ford Cruller, they'll get to visit a new world in Cassie's Collection. The giant library is filled with story revelations about the eccentric beekeeper, but it also contains its fair share of collectibles to grab.

While there are five pieces of Emotional Baggage to recover, players will also be tasked with finding four Nuggets of Wisdom, two Memory Vaults, and two Half-A-Minds, with each collectible scattered throughout Cassie O'Pia's mental realm. Finding them all won't be easy, with Cassie hiding the collectibles in some hard-to-spot locations that Psychonauts 2 players can easily miss.

So, for those struggling to find all of the secrets Cassie's Collection has to offer, here's the location of every Nugget of Wisdom, Memory Vault, and Half-A-Mind lurking within the colossal library.

Nuggets of Wisdom

As mentioned prior, there are four Nuggets of Wisdom to be found throughout Cassie's Collection. This time around, they're shaped like quills in pots of ink, and as usual, will glow and emit a faint sound when players are near them.

The first Nugget of Wisdom can be found in the very first area of the level. When facing the receptionist, the Nugget of Wisdom can be found directly behind the player. To reach it, they can climb on a ledge to their right and then hop across the pile of books and filing cabinet in front of the trinket to grab it.

Nugget of Wisdom number two is found right after players navigate through the second book. Once they've exited the novel's platforming section, they'll arrive at the Deep Inside Teacher's Domain area and, after battling some enemies that spawn in the area, have to jump across two smaller books to access a large book with a gust of wind emerging from its center. Instead of riding the gust of wind with the Levitation ability, use Mental Connection on the thought chain to the left and ride it to the top of the area. At the end of the chain, players will find the second Nugget of Wisdom on a ledge.

The next two Nuggets of Wisdom crop up in the Waterfront area. The third Nugget can be found when Raz enters the Fish Market to find Exhibit B of the evidence against Fannie Flats. Players should head over to the railing to the left and walk onto the nearby bookmark with a cat on it. If they angle the camera, they should be able to see the third Nugget of Wisdom tucked away in a small crevice. Jump off the bookmark and use the Levitation ability to soar into the small area and grab the trinket.

The final Nugget of Wisdom is the easiest to find of the four. After Raz has grabbed Exhibit C of the evidence against Fannie Flats, he'll emerge on a rooftop with a railing that takes him back to the main part of the Waterfront. To the right of the railing will be the Nugget of Wisdom.

Half-A-Minds

The two Half-A-Minds scattered throughout Cassie's Collection shouldn't be too difficult to come across. As per usual, collecting the pair will allow Raz to upgrade his health.

The first Half-A-Mind in the level is found after Raz begins his quest to locate the Librarian's restricted books. Follow the level's main path until coming across the first interactable book. To the right of it will be a locked door with the Half-A-Mind behind it. If this is a first run-through of the level, keep note of where the brain can be found, as Teacher Cassie will give Raz the Projection skill in the next room, allowing him to open the locked door.

As for the second Half-A-Mind, it can be found after delivering the first book to the librarian and setting out to find the second book. After using Projection to enter the locked door to Literature Lane in the Librarian's Desk area, players can find the Half-A-Mind on the right-hand side of the room. Pick it up to upgrade Raz's health.

Memory Vaults

The two Memory Vaults in Cassie's Collection offer some new story details on Cassie O'Pia's encounter with Maligula and her relationship with other members of the Psychic Six, so they're worth seeking out. As always, players will have to break the safes to access the memories.

The first Memory Vault is found in the same area as the second Nugget of Wisdom. After exiting the second book and entering the Deep Inside Teacher's Domain area, players will find the vault to the left of where they spawn.

The second Memory Vault is found during the Waterfront section. In the area where Raz can find Exhibit A of the evidence against Fannie Flats, players will find some climbable stamps leading up to a platform with a grindable rail and an archway to the left. Head through the archway, follow the path, jump over the curved pencil, and head left. There will be a portal in the back of the book the players are next to. Head through it and climb up the stack of books beside the portal to find the Memory Vault.

With that done, every Nugget of Wisdom, Half-A-Mind, and Memory Vault should be accounted for. Players can now return to Raz's quest to defeat Maligula or hang back and look for the level's Emotional Baggage.
