Hello everyone! For those who are bored of there being just the Overworld, Nether, and End, or those who want to get diamonds and other loot quicker, or interested in a world of rabbits, this may be one of those datapacks.

Advancement/Challenge
There will be a challenge completed as soon as you enter the new dimension.
There will be a challenge completed when you survive for 2 days.
There will be a challenge completed when you return to the overworld.

Dimension
It's more like the Overworld than the Nether and End. Snow golems won't melt. Water won't evaporate. Maps and compasses will still work. Piglins and Hoglins won't zombify. Beds and respawn anchors will work, but you won't be able to sleep through the night. Raids can still happen from Bad Omen in here if you managed to transport villagers into here. The dimension has a daylight cycle same duration as the Overworld. At night, mobs can spawn at up to light level 15. There is plenty of deepslate to find. The portal teleports you to Y 208 from where you are.

Biomes
Woods- Has giant trees with cyan leaves and drop carrots. Spawns piles of light blocks and diamonds. The grass and fog are cyan/blue. Bees, Rabbits, Chickens, Allays, and Strays spawn.

Plains- Similar to the cherry grove but with light blue grass and fog. Cherry leaves drop carrots.

Peaks/Old Growth Woods- Similar to regular woods, but white.

River- Like a frozen river, but with coral and sea pickles.

Forbidden Fijord- Like a snowy soul sand valley, but it only spawns wither skeletons.

Loot Tables
-Weapons
-Armor (Drops armor and mob heads with mixed enchants and certain buffs like speed boost, health boost, and knockback resistance)
-Warren chest loot (Carrots, Pies, Sugarcane, Saplings, Raw Ores, Ingots, Crystals, Netherite, Blaze Rods, and more)
-Warren shrine loot (From a sus gravel block, you will get a certain weapon or combat item)

Functions
-load (places a portal right where you are)
-tick (constantly schedules example and hunt functions)
-portal, start, and finish (Transports any entities to the dimension and back)
-arena (functions recommended to use in the arena)
-revenge (summons lightning on rabbit loot such as meat, hides, stews, and feet)

The portal function will check every 5 seconds if any entity is standing on a chiseled deepslate and also in powdered snow. If that's true, then the entity teleports from where they are to Y level 208 in the dimension. The function also may give you slow falling. Let's hope it does.

The arena functions spawn based on their name:
-arena/summon_all (summons all 5 mobs, except for boss)
-arena/summon_boss (summons MASTER STRAY)
-arena/decide (all duelers will decide what to do based on their situation, switch weapons, give each other boosts)
WARNING: Summoning a dueler or boss will set the nearest player to adventure mode!

THE BOSS SUMMONS LIGHTNING AND DEALS LOTS OF DAMAGE!!!

Structures
-Hut
-Arena

The hut will spawn with warren chest loot and shrine loot in a sus gravel on the ceiling. The arena has a powder snow floor, ice floor, soul sand floor, and trampoline.

Hope this is a good datapack and you don't die quickly from the Killer Bunnies or die from falling off a tall tree.

UNZIP THE FILE IF THERE'S NO PORTAL AT SPAWN OR ANY COMMAND SUGGESTION THAT HAS "wyhaworld" IN IT

Note that the hat the boss is wearing is an experimental texture pack I'm working on.
