This mod has many weapons and tools from the show Gravity Falls including: The Memory Gun, the Magnet Gun, Fun Dip, Infinity Pizza, the Infinity-Sided Die, the Laser Arm Cannon, and many more.

Dimensions: You can teleport to the future using: '/tpdim 2' or the nightmare realm using: '/tpdim 3'. The '/tpdim' command can also be used to teleport to any dimension.

Here is a mod review by Alex Funlord: https://www.youtube.com/watch?v=8jQmrhdqVnU

A couple things are missing in this mod review but you should definitely watch it if you are confused on how this mod works.

Blocks:

Crystal:

A crystal that when mined will drop the crystal shard. Spawns on top of grass blocks in Gravity Falls Biomes. Any entity that walks near this has a chance of randomly growing or shrinking.

Uranium Ore:

This will later be used to power the inter-dimensional portal. Generates between layers 1 and 10 in any biome. A total of 12 uranium ore will be needed for creating the inter-dimensional portal. You need a uranium suit when walking near this or the Uranium tank or else you will be poisoned.

UraniumTank:

Used for holding liquid Uranium

UraniumFurnace:

Using a bucket of water and 3 uranium ore, this allows you to create a bucket of uranium.

The Laptop:

Fiddleford's laptop requires a password that when entered unlocks the computer. The laptop is opened and closed by right clicking it; to look at the computer screen you have to hold 'ctrl' and right click it. If the inter-dimensional portal is on, the laptop will have a countdown screen.

Copper Ore:

About as common as iron, this ore, when smelted, is one of the items needed to craft batteries.

Colored Lights:

There are 16 colored lights that glow as bright as glowstone. To craft them you use the colored glass of your choice and glowstone.

Unicorn Hair: Obtained by killing Unicorns, this hair can be placed down to protect you from the weirdness of Gravity Falls. Surrounding your house with this hair will prevent Bill, his minions, or any other magical creature from entering your home (except for the unicorn itself of course).

Power Cord: Connect a power cord between the hyperdrive and the lever as one of the steps to create the portal.

Hyper Drive: Used to power powercords - to power place a full tank of Uranium on both sides of the HyperDrive. The HyperDrive can't be crafted - you must get it the same way Ford did.

Portal Control: Right click this with a journal in your hand to put that journal on it. All three journals must be on the PortalControl for the portal to work.

NowUSeeitNowUDontium: The only reference of it that I have found of this is in Journal 3. This is the material that powers the Quantum Destabilizer. It can be found deep underground in the Overworld and it looks almost transparent so it can be hard to see.

Items:

Journals 1-3:

Each of these can be right clicked, while holding the left control button, to see part of the portal instructions - will later be used to make the inter-dimensional rift. All of the books now have at least 7 pages each from the show. The books can also be placed like blocks in case you want to show off your collection of journals to your friends. (Most of the journal pages are from Journal 3 because that is what is shown in the show the most, however I spread the pages throughout all three journals - I hope this isn't a big deal for anyone.) (And many thanks to creaperking20020 for this idea.)

Journal 3:

If you go to the undead page in Journal3 and hold the 'Item 1' key while it is night time, zombies will starts spawning in the area around you until it becomes day again.

Crystal Shard:

Used for crafting the magic flashlight .

Grappling Hook:

Pulls the player towards the block they are clicking towards - has a limited range.

InfinitySidedDie:

When you roll this dice just about anything can happen; you can be given a diamond block, be teleported to the nether, or you can just roll an 8.

LaserArmCannon:

Very similar to a bow except that it shoots in a straight line instead of bending towards the ground. Requires batteries to recharge.

Latex:

When smelted creates rubber.

Rubber:

Used for making the Hazmat Suit.

Memory Gun:

If a mob is shot with this, all of its memory will be erased (doesn't work on the ender dragon as the ender dragon runs on a rail system and doesn't have a true AI). The memory gun requires batteries to recharge it.

LightBulb:

Ammo for the Memory Gun

Magnet Gun:

Pulls the player towards any block that contains iron - has no range limit. Has the ability to pull iron trapdoors out of the ground (like Ford did in season 2 episode 17).

Quantum Destabilizer:

Instantly kills any mob. Requires 1 diamond per shot.

Time Wish:

Used for crafting some amazing items. Or if eaten it will give you godly potion effects (though making an infinite slice of pizza would be a much better use of it).

Uranium Bucket:

Used for transferring liquid uranium from the Uranium Furnace to the Uranium Tank.

Records:

There are 5 records in the game that can be played using a normal jukebox. The original theme song, the rock theme song from when they are fighting Bill, Straight Blanchin, Disco Girl, and the weirdmageddon theme.

Battery:

Batteries are used for crafting electronics and for powering them. Using most electronic items will use up energy. If you have a battery in your inventory, you press 'R' while holding the item you want to put a battery into. They are crafted using 3 copper, 3 redstone, and 3 iron.

Leaf blower:

The leaf blower isn't that practical of an item, but it is quite useful at keeping gnomes and other mobs at bay. The leaf blower requires batteries to operate.

Time Tape:

Allows the user to teleport to the future by right clicking (the dimension isn't finished yet). If you hold 'R' and move forward or backward you can control the time of day.

The President's Key:

This key allows you to easily open iron doors and iron trapdoors. (I am open to any suggestions for what other powers this key should have.)

Flashlight:

The flash light, once turned on by right clicking, illuminates the area around you so you have a light source on the go. The flashlight requires batteries to recharge once you have used it for a while. If the flashlight is still on while in your inventory, the battery will still drain even though it isn't lighting up your surroundings.

Black Light:

When this is in your inventory and you read the journals, it will reveal the invisible ink. Will also reveal invisible ink on books that have been placed on the Portal Control.

Net:

This net can be used to capture small floating eyeballs.

Return Device:

This device must be crafted before entering the Inter-dimensional Portal because it is the only way back! The return device connects to any active portals in the overworld so you can use it to easily get around. However if there are no active portals in the overworld you will not be able to return home. Also the device can only see the first 15 or so portals active, but that shouldn't be an issue unless you are playing on a large server.

Magic Flashlight:

Changes your apparent size. (Doesn't yet change your hitbox). Press 'Item 1' to grow when the flashlight is on and press 'Item 2' to shrink. Pressing both buttons at the same time will return you to your normal size. Pointing it at an entity and right clicking will change the entity to the size set in the flashlight - press the grow or shrink button to then shrink or grow the entity.

Food:

Infinity Pizza:

A slice of pizza that never runs out.

Smile Dip:

A candy that gives the player haste and speed, but also gives nausea.

Armor:

Dipper's Armor:

Gives Luck when fully equipped

Mabel's Armor:

Gives Speed when fully equipped

Cloak of Occasional Invisibility:

Occasionally makes the player invisible

Hazmat Suit:

Allows the player to carry uranium without dying of radiation

Magical Armor:

All of the following armor items need a Time Wish to be created.

Speed Boots: The speed boots are controlled using the 'Armor 1' and 'Armor 2' Keys. Pressing these keys will control how fast you go. These boots allow you to run up walls and they negate all fall damage.

Regeneration Legs: Gives the user regeneration and a jump boost.

Strength Chestplate: Gives the user strength and haste.

Fire Helmet: Gives the user fire resistance and water breathing.

Stan's Golden Knuckles:

Stan's golden knuckles can be crafted using 3 gold blocks and 2 gold ingots. When equipped in the armor slot it gives the user increased strength.

Mystic Amulet:

The mystic amulet is a powerful necklace that gives the user the ability to pick up mobs (using the 'Item 1' key) and the ability to throw mobs once picked up (using the 'Item 2' key).

Tie of Possession:

Allows you to control other mobs. To use you must right click a mob with a tie of possession and then put the tie on. Use the arrow keys to move the mob. Use the 'Armor 1' and 'Armor 2' keys to turn the mob. If it is a creeper use the 'Armor 3' key to make the creeper explode.

Entities:

Gnomes

These creatures are mobs that act like zombie pigmen. If you attack one of them, all of the surrounding gnomes will also start to chase you. They usually drop carrots, rarely drop gold, and extremely rarely drop an enchantment table. (Their current ambient sound is just a joke - I'll change it to a real gnome sound before the final release.) They naturally spawn in the Gravity Falls biome in groups of 10 - 20.

Lolph and Dundgren

These guys can drop the Time Tape or Laser Arm Cannon when killed. They have the ability to teleport around at will. You should be well armed if you chose to attack them because they are strong and have a decent amount of health. The two mobs are very similar to each other except that Lolph is a bit faster and Dundgren is a bit stronger.

The Hide-Behind

The Hide-Behind can only be seen if you are in creative mode. If you try to look at him in survival mode he will run from view. (Not sure what else this mob should be able to do.)

Unicorn

This creature naturally spawns in the Gravity Falls Biome and drops unicorn hair when killed. It is a neutral mob so it will only attack you if you attack first.

Bill

Bill is the most powerful mob in the game (obviously), so do not try to fight him unless you are very prepared. Bill can be summoned by placing journal 2 on the ground and surrounding it with torches.

Keyhole and Eightball

These two guys are Bill's minions so they put up a good fight, but they won't come into the overworld unless they are let in.

The Golf Cart

The golf cart is like a motorized horse which allows you to easily travel around your world. The golf cart needs to be powered with batteries. It's inventory can be accessed by shift clicking the the golf cart while outside of it. It can also store a few items in it's inventory.

The Eyebats

The eyebat is a nice little creature that roams free in the Gravity Falls biome, and has a big brother in the Nightmare Realm.

Security Droid

This robot was made by a highly advanced civilization millions of years ago and still guards the UFO it was built to defend.

Time Baby

You must defeat Time Baby in Gladiatorial Time Combat to win a Time Wish. He is very powerful so don't fight him without a strategy.

Evil Tree Creature

In the Nightmare Realm some of the trees may attack you when you try to get some wood, so be prepared to fight back.

Structures:

MysteryShack (1980's)

When Ford moved to Gravity Falls in the 80s he needed to build a house to work at. Equipped with stay-out signs, weird contraptions, journal 1, and a secret entrance to an incomplete inter-dimensional portal, this is a great place to call home.

Journal 3 Tree

This is the tree that Dipper stumbled upon which opened a door to journal 3. This tree looks very similar to all the other trees, except for having a lever on it - so keep a keen eye if you want to find it. (Since the tree is made out of metal, you can use to magnet gun to find it more easily.)

The Bunker

This is where Stanford and F did most of their research in secret. It contains journal 2 and food that will last a lifetime! Currently there is no trap so you don't need to worry about that. It is fairly easy to spot because the entrance is a short redwood tree.

The UFO

A UFO landed about 30 million years ago, and has been hidden underneath the soil ever since. There is an entrance right in the center of the crash site if you remove the dirt on top. In the UFO there are 2 Magnet Guns, but watch out for the motion sensors.

Key Binding Defaults:

Item 1: 'G'

Item 2: 'V'

Armor 1: 'B'

Armor 2: 'N'

Armor 3: 'M'

Battery: 'R'
