Yep, Professor Frankly comes to the Mushroom Kingdom from Rogueport to begin a "Tattle Library" in a certain location not revealed yet.

A "Tattle Library" it's a library in which there's data of all enemies in Star Bits Journey. Professor Frankly gives you a sidequest of getting all the data of the enemies all around the game when you show to him that you have a Tattle Badge, which gives the ability to Tattle enemies and get their information to the tattle log in the info menu. Surely, after getting data of all enemies, including bosses, he will give you a rare item, badge, or even a rare emblem. If you passed a boss that you didn't tattled, you can go to the Archives Ruins to find the data of the bosses you haven't tattled and buy them for a very high price, but only bosses you have encountered will appear on the list, not the bosses you havn't encountered yet.

Any more suggestions, improvements, deletions, innovations to this feature? Discuss!

This sounds awesome!

because it is

maybe you can make it cooler if he gaves you the chance to repeat the battle if you got the tattle of it, like a challenge of beating Bosses in certain number of turns

maybe i can let use a boss battle mode when you get all the tattles besides the special reward. thanks, muti!
