Special world seeds
Special world seeds are world creation modifiers that alter the created world in strange or unique ways. This feature was previously named secret world seeds, but those are now an entirely new feature.
Unlike regular world seeds, which only affect the usual world structure, special seeds can produce worlds with characteristics that would not be attainable through normal world generation (i.e., they can affect the game's mechanics while playing in that world). For instance, they may change enemy statistics and behavior, item drops, graphics, theme music, and more. Special world seeds are only available in the World Seed Menu, which is accessible by clicking the seed icon next to World Seed during world creation.
There are 9 different special seeds. Any number of special seeds can be combined, forming a combination special seed. Some of these combinations have additional unique effects.
Not the Bees
- Seeds (case-insensitive):[1]
not the beesnot the bees!notthebees
This seed generates a world dominated by bee-themed biomes and bee-related items and structures.
Most of the world is replaced with the Jungle biome, with Hive and Honey Blocks found in abundance, and Larvae spawn throughout the world. The Merchant replaces the Guide as the starting NPC.
While generating
- All generation descriptions say "Generating bees".
World icons
The world icon of a Not the Bees world is a Mahogany tree surrounded by Bees.

- Seeds:[2]
051620205162020
This seed references May 16, 2020, which is Terraria's 9th birthday and the release date of 1.4.0.1. It invokes a highly extraordinary world generation referred to in the source code as drunkWorldGen.[3] It has therefore come to be referred to by the Terraria community as drunk world.
In this seed, both evil biomes will generate, as well as both variants of any ore that comes in two varieties. The Party Girl replaces the Guide as the starting NPC, and the Dungeon entrance is now generated under a Living Tree with brown painted leaves. The Snow Biome and the Jungle Biome will be generated on the same side of the world.
While generating
- Generation descriptions and tips become random numbers that change every tick (except when "Placing traps").
- The background shows a Glowing Mushroom biome, with clouds that resemble Redigit's head. The moon moves backward and resembles a smiley face (see Trivia). Once the world finishes generating, it is possible to go back to the main menu with these effects still visible.
- The outline of the progress bar rapidly flashes between Corruption and Crimson.
- The Console Title music plays, instead of the normal Title Screen music.
- The Terraria logo spins out and disappears along with the version number.
- The time of the day is always night, and it never turns into day.
World icons

Celebration MK 10
- Seeds (case-insensitive):[4]
celebrationmk10051620115162011051620215162021
This seed celebrates Terraria's tenth birthday, on May 16, 2021, and generates a world that offers several unique and highly beneficial features for players.
The player's spawn point is on the beach of one Ocean. Andrew the Guide, Whitney the Steampunker, Yorai the Princess, the Party Girl, and an Angora Town Bunny will also spawn there and a Party immediately starts. A majority of the world is painted in bright colors.
Items in chests always have a "best" modifier such as Menacing or Legendary.
Two unique enemies can be encountered in this seed:
- The Jungle Mimic can be found in the Hardmode Jungle.
- Golden Slimes can rarely spawn.
The chance of obtaining rare items (such as the Rod of Discord and developer items) is substantially increased, the Traveling Merchant always sells 2 extra items, and the Princess sells rare items (such as the Slime Staff and Discount Card).
While generating
- All generation descriptions and tips become pink.
- The Underground Hallow music will be played.
World icons
The world icon of a Celebration MK 10 world is a Pink Sakura tree with a blue bowknot.

The Constant
- Seeds (case-insensitive):[1]
constanttheconstantthe constanteye4aneyeeyeforaneye
This seed is part of the crossover with Klei Entertainment's Don't Starve Together.
It introduces hunger and darkness mechanics that make the early game especially challenging. Marble biomes with statues and Spider Nests will generate on the surface, and Cacti will damage the player.
The entire game uses a dark sepia shader that gives the game a gloomier look, similar to the shader applied by the Radio Thing. Equipping the Radio Thing will then cancel this shader instead. This shader is not visible if the player has the lighting mode set to Retro or Trippy in their video settings. Items that are Don't Starve crossover content are more likely to drop from enemies.
While generating
- The generation description "Generating wavy caves" is added.
- A constant shader that significantly darkens the screen will be applied.
World icons
The world icon of a Constant world is an Evergreen from Don't Starve.

For the Worthy
.png)
- Seeds (case-insensitive):[1]
for the worthyfortheworthy
This special world's features aim to drastically increase the difficulty of the game.
This seed increases the world difficulty by one level (e.g. a Classic Mode For the Worthy world is equivalent to a normal Expert Mode world). Master Mode worlds using this seed will display as having "Legendary" difficulty on the world select menu.
All enemies' contact damage, health, and coin drop rates are increased, in addition to the world difficulty multiplier, by their standard amount in a Classic world.[5] Enemies' contact damage in Master Mode worlds is further multiplied by 4/3.[6] Damage from ranged attacks (i.e. projectiles) is unchanged.
Bunnies (even when placed) and Demons have a 2/3 (66.67%) chance to be replaced with Explosive Bunnies and Voodoo Demons, respectively.[7] The Demolitionist replaces the Guide as the starting NPC.
There are also many other changes to world generations and game mechanics. For instance, some water pools throughout the world are replaced with lava. Pots and trees may drop lit Bombs that shortly explode, instead of their usual items. Skyware Chests are replaced with locked Gold Chests, but still have their respective loot.
Bosses also receive changes to their size and/or AI that make their battles much more difficult.
While generating
- All generation descriptions and tips are spelled backwards.
World icons
The world icon of a For the Worthy world is a Yellow Willow tree.
Pre-Hardmode Corruption world icon.
Pre-Hardmode Crimson world icon.

No Traps
- Seeds (case-insensitive):[1]
no trapsnotraps
This seed generates a world with significantly more traps than a normal world. It also contains new traps, including Bouncy Boulders, Life Crystal Boulders, and TNT Barrels.
While generating
- The generation description "Placing traps" is replaced with "Not placing traps".
World icons
The world icon of a No Traps world is identical to the regular icon, only with Wire coming from the tree's bottom.
Pre-Hardmode Corruption world icon.
Pre-Hardmode Crimson world icon.

Remix
- Seeds (case-insensitive):[1]
don't dig updont dig updontdigup
This seed flips the usual order of player progression through biomes by having the player spawn in the central part of the Underworld. Above that are, in order, a Glowing Mushroom biome, an underground version of the Surface biomes, the Underground layer, the Cavern layer, and finally the "true surface" which is entirely contaminated by the evil biome, without a sun. The Tax Collector replaces the Guide as the starting NPC.
A flat Ash Block "island" is generated in the central part of the Underworld, with Ash Trees growing and lava not spawning at all. Mimics now spawn in pre-Hardmode, but drop Gold Chest loot during this period instead. Plus, slimes have a chance to contain Fallen Stars as their bonus drop, and they can also spawn from broken Pots (such ones will always contain a Fallen Star). In addition, Lava Slimes do not generate lava upon death in Expert Mode and above.
While generating
- The Terraria logo rotates and flips upside down.
- The background turns into the starry sky background of Space.
- The Corruption music will be played, regardless of world evil.
World icons
The world icon of a Remix world is an Ash tree.
Pre-Hardmode Corruption world icon.

Zenith
- Seeds (case-insensitive):[1]
get fixed boigetfixedboi
This seed is a combination of Drunk, Not the Bees, For the Worthy, Celebration MK 10, The Constant, No Traps, and Remix seeds, making it the most challenging world for player progression.
It also contains unique features, including the boss Mechdusa, which replaces the mechanical bosses in progression, as well as features like Crispy Honey Blocks that burn the player and release lava when mined.
While generating
The generating screen combines features of the other seeds:
- The outline of the progress bar rapidly flashes between Corruption and Crimson.
- Most generation descriptions and tips are displayed backwards, except for "Not placing traps".
- The Terraria logo rotates and flips upside down.
- The background turns into the starry sky background of Space.
- The Otherworldly Space music will be played.
- A star minigame is initiated: reflecting falling stars with the cursor will increase the spawn rate of certain objects and structures during world generation.
- The cursor becomes the "smiley moon" seen during the drunk world's generation. Any falling stars in the background that hit the moon will be reflected, making a cat sound (same as the Meowmere's projectiles) and the sound of coins being picked up at the same time.
- The shader effect similar to The Constant seed will be applied, and gets more obvious as the stars are reflected.
World icons
The world icon of a Zenith world is a flickering, glitchy tree that shows multiple versions of the standard tree icon, with different combinations of colors. Unlike other world icons, the icon does not change with player progression.

Skyblock
- Seeds (case-insensitive):[1]
skyblocksky block
This seed makes the player spawn on a small sky island where the player have to kill slimes and build out from the island to reach other islands inside of the world. One of these island is a Shimmer island close to the edge of the world with a Music Box (Aether) and an Aether Monolith. This island does not spawn if For the Worthy is active, unless Celebration MK 10 is also active (the Aether will always spawn on a Zenith + Skyblock world).
While generating
- World generation takes much less time due to the lack of terrain.
World icons
The world icon of a Skyblock world is a cloud shaped like a tree.

Notes
- The seed being randomized can technically lead the game to create a Drunk world or a Celebration MK 10 world without specifying the seed, but the chances of it happening are astronomically low (1/2,147,483,648 (0.000000047%) for the drunk world, 1/1,073,741,824 (0.000000093%) for the Celebrationmk10 seed).
- This is due to the random seed being a random number between 0 and 2147483647; the random seed can match the one needed for one of these special seeds. The chances are doubled for the Celebrationmk10 seed due to the fact that two seed numbers trigger the special seed.
Achievements
ExplorerTrivia
- The smiley-faced moon seen during the generation of a drunk world is a reference to an astronomy hoax that was said to happen the same day Journey's End was released on PC.[8][9]
- Unlike the other special seeds, the Drunk world and Celebration MK 10 world seeds are interpreted as numbers, so any number of 0s can be added in the front (e.g.
000005162020for the drunk world). In addition, there are numerous unintended strings that generate these two special seeds (due to the use of the CRC-32 algorithm[10]), such as:- Drunk world (case-sensitive):
now aunt brushJoke Disappear Horizondisapprove stiff solution
- Celebrationmk10 (case-sensitive):
Thirst of dressengineer governor reproductioninform Representative yorai
- Coincidentally, the third seed references Yoraiz0r, a Terraria programmer.
- Drunk world (case-sensitive):
- If a modified world were to have 2 or more active special seeds at the same time, the icon for it would follow this priority: Zenith > Drunk > For the Worthy > Not the Bees > Celebration MK 10 > The Constant > Remix > No Traps.
