Memory Book

Memory Book is a feature in Yeah Jam Fury: U, Me, Everybody! consisting of a notebook used by the three main protagonists: Yeah, Jam, and Fury. They use the Memory Book as a journal to log their adventures and communicate with each other, due to being unable to do so normally. As a feature, the player can use it to check the stickers they've unlocked, their gameplay statistics, and an unlockable cutscene.

Entries
Entries are the passages in the Memory Book that the three alter egos write with each other. Each entry is unlocked by unlocking its corresponding sticker, each of which has a unique image, name, and unlock requirement. With the exception of four secret entries, all of their names and requirements can be previewed in the Memory Book before being unlocked, but to view their images and the entries themselves, the player must unlock the stickers.

There are 50 entries and stickers in total, and each is tied to a corresponding achievement sharing the same name, image, and unlock criteria.
