So, BFDIA 13 has so many little lore drops in it like for example, It's explains how Firey turns back to normal between BFDIA 12 to IDFB.

It explains why the assets change in IDFB.

It explains how Dora didn't die in the the LOL

It explains why there's a random cookie in the Science Museum

It confirms that Firey did recover Leafy

and It confirms that Leafy and Evil Leafy are 2 different people

Sorry for the rant
