Everyone likes Gravity falls, right? and if you don't, then you're lying to yourself (angry face)

Ok, ok, so hear me out... Gravity. Falls. Mod!

Obviously, it's mostly a mob based mod, but it could be sooo cool!!!

could include NPCs like Soos, Wendy, who sell you Mystery Shack themes items like bobble heads and snow globes.
Stan and Ford who could... Do something... (I havent thought of that bit yet) and Waddles... for no reason at all!

Passive-Aggressive mobs include Eye Bats, Gnomes, Vampires, Zombies (different to Vanilla Zombies), Ghosts, unicorns, Multibear, etc. Who all attack when threatened, similar to Endermen

could include bosses like (obviously) Bill, 8 Ball and the other Henchmaniacs, Blendin and the other Time Anomaly Removal Crew members (which could play in nicely to the Dalek Mod)

Naturally Spawning structers could include the Mystery Shack, Alien Spaceships (where Alien Adhesive can be found), and other Gravity Falls landmarks.

depending on how invested you are in making the mod, you could even include Fords Portal, which could take you to the multiverse. or, similar to the Schism in the Dalek Mod, it could just be a structure that maybe occasionally gives debuffs like Blindness and nausea when you look into it for too long

Items include the Journals (obviously quite hard to get) which could provide a map/ compass for when you're lost, information on all mythical creatues, and a book and quill sort of section to add your own entries.

Stan Bobbleheads, snow globes and fake attractions for decorative items

and a Question Mark Shirt, Stans Fez, Fords Glasses, Mable's sweater, Dipper's hat (side note, did anyone else know his real name is Mason?! like, Mason and Mable, cute choise), etc, for clothing items

Food which I haven't put much thought into could) could include Smile Dip, which gives you nausea, and the infinity Pizza, which is a single slice of pizza, but with a durablity instead of running out after one bite.

Weapons include Gideon's telekinetic Amulet, some sort of item to give you Bill's powers, Fords Magnetic gun, and the memory wiper, and (when used in all together) the Journals.

Also, just for fun, can we add Dippy Fresh? He'll have like, 1 hp, and his only purpose will be to die.... I just HATE him soo much!

For the record, I literally spent like, two mins thinking about before I thought SOME NEEDS TO HEAR THIS!!

but, although not much thought has gone into it, I would literally figuratively make a deal with Bill Cipher to get this to happen!!
