Well Traveled Achievements - Mementos

[Peridot]

I've compared my screenshot with others, and I'm only missing one thing: the pink books next to the bibi-lure.

Anyone know what triggers this?
I've done all quests, only flowers left (and they seem neverending?)
I've read all the library books
I've talked to everyone on plumpet island with all characters

here is someones screenshot for all the mementos so you can compare your own:

Talk to Almagest, he's on the the bridge outside the Owl Library. You can talk to him several times during the game but the memento will only show up if you talk to him again near the end of the game. It's possibly linked to either Locke's last fight or you having explored everywhere.

Thank you Karinms :)

So I'm not getting any change in dialogue. Do I have to replay the entire game and get each different text he says? This is the last thing I have to do.

No, you shouldn't need to.
You talk to him near the end to "activate" the last memento in your collection.

Is it the pink books you are missing?
that is the final memento,
if you're missing something else, it could be an optional boss you haven't defeated?

How can I collect the thing on top left in the picture?
