Once Froggy and Cotty went to the forest for mushrooms...
"Fairy Kingdom of King Froggold II: Very Dark Forest" is a prequel to the game from "FKOKFII: Super Garden", made by Bonnie198. The author of the game himself came up with its prequel and it is not official.
King Froggold II was going to invite his cousin King Sungold, and it looks like a big party is coming! Froggy and Kitty heard about this and ran to tell others. And from that moment the adventure began!
This story is not related to the main lore of Five Nights with Froggy and is not a continuation of it!
