You don't need to fill the library for any endings, and the rewards can be gotten elsewhere.Think it may that the Library hasn't been fully filled. I'm still lacking [Elizaboth Bathory] ; [Black Rabbit of Inaba] ;
[The Fox and the Grapes] ; [The Jumper] ; [Wolf and XX Goats] ; [Wizard of Oz] ; [Mt Kachi Kachi] ; [Goose that laid golden eggs] and finally [Pinochio].
If anyone's got a list of where the fairy tale lads are located or know where one of these speficic ones hide in which area, then do let me know. I'd be mighty grateful.
Jumper is a 3 parter. You have to kill a grasshopper, a frog, and a flea. The flea is pretty hard to see so I'll just tell you he is in upper Ludwidge near a bench. Wolf and goats is in a well near the bonfire that Pumpkin O is first by. Fox and the grapes is part of Griffy's sidequest. You fight a mad spirit with her in the upper right of the rose garden maze. You need to do this right after the cathedral event.
Completing G route does allow this but it also unlocks the dlc 3 scenes which you can't normally get until after G end.That all said, I hope the hidden route will unlock that 'opens all of the gallery' that the true ending of BS1 did. That was pretty nifty if not rewarding. Still this game as a whole is real fun, and again, it's a real pleasure to be here.
