Although it should be noted that even though the difficulty level labels Pranksters Paradise AFTER The Grid, The Journal, Dive Order, And Keyblade order all imply that the Story for Prankster's Paradise comes before the Grid
As you beat the worlds, the level of difficulty of the remaining worlds change. So if you go to La Cite Des Cloches first, Pranksters Paradise becomes a higher level than The Grid.
It's originally like this;
La Cite Des Cloches - Pranksters Paradise - The Grid.
That's the level of difficulty from lowest to highest, but if you go to Notre Dame first, then it changes to this;
La Cite Des Cloches - The Grid - Pranksters Paradise.
I noticed this when watching a playthrough for the Japanese version.
The level of difficulty depends on which world you go to previously.
