- There used to be a map called Last Cave that mysteriously made you crash and take control of someone's character without their knowledge if you traveled too far.
- Bonfire Island was a map carried over from the original Impressive Title. It was the original starting map before Lonely Cave was created. Because of this, various different types of RPs took place in the map, infamously the horse and TLK roleplays in very specific areas.
- A lot of inappropriate names/characters and events were popular in the first two years FH has been online, primarily in Bonfire Island. This died down when rules were made against it.
- Roar and howl actions were added into the game a year after the release. Beforehand we used the rage emote to indicate roaring for felines.
- KovuLKD (the owner/developer) originally planned this game to be a realistically-styled MMORPG with NPCs and Quests.
- A feather tail was originally an option in the very early release in the game, but was removed due to controversy.
- Warrior cat roleplays were very popular in the top regions of Fluorite plains and didn't occur in any other map as far as I know.
- There was a waterfall in Ficho tunnels which was nearly impossible to get up on unless you took screenshots to purposefully lag spike the game. Dashing made it much more easier when it was added into the game.
- FH+ was a remake of the game by TLK4EVR/Simba. It had new textures, objects, and maps. Unfortunately the creator lost his files and it hasn't been resurfaced since then.
