Grand Library

The Grand Library is a location accessed by the Air Balloon Platform after the 6-star upgrade.

Catacomb Tree
The Catacomb Tree is an area outside the Grand Library that allows capture of rare bug species, regardless of the current season. It can be regarded as a Bug catching counterpart to Captain Georgie's fishing trips.

Summoning bugs at the Catacomb Tree requires Gooeybomb, obtainable after reaching Level 30 Bug Catching and then through talking to Petunia.

The Catacomb Tree is reset daily. With one use of the Gooeybomb, the Catacomb Tree spawns 3 types of bugs or items. Feeding the tree will move each spawn option one item clockwise on the wheel. Spawning bugs is free while feeding the tree costs with a feed limit of 3 per day. This limit is removed once you obtain the Perfect Gooeybomb from Petunia for reaching Level 60 Bug Catching.

The following Bugs may be caught here at the Catacomb Tree:

Other items
You may also be able to find these other items while fishing.

Books
Books are collectible items obtained as the third Traveler Gift from traveler NPCs. They can be found in the interior of the Grand Library, overlooked by Bookmaster Yugri.

Once a book has been obtained from their respective traveler, the traveler NPC can be found idle in the interior of the Grand Library.

24 books are needed to unlock travel to the Edge of Solemn.
