World generation changes
Overall
- The spawn point is changed to either Ocean in the world, implying most of the spawns usually happening in the inner third of the world will happen in the left or right sixth of the world.
- Andrew the Guide, Whitney the Steampunker, Yorai the Princess, Amanda the Party Girl, and an Angora Town Bunny will also spawn there and a Party immediately starts.
- A majority of the world is painted: The Dungeon is in deep pink, Living Trees, the Pyramid, and Clouds on Floating Island are painted in pink, the Jungle Temple is painted with purple tiles and cyan walls, and all Sand Blocks, grass, and surface objects are painted in cyan.
- There are even more Living Trees than in a drunk world.
- Items in Chests always have a "best" modifier[2].
- Accessories will have one of the +4 modifiers (Lucky, Menacing, Quick, Warding).
- Weapons will have modifiers with the most stat increases, according to their damage type. The possible modifiers are:
- Legendary, Godly, or Ruthless for melee weapons
- Unreal, Demonic, or Ruthless for ranged weapons
- Mythical, Demonic, or Ruthless for magic and summon weapons
- Half of the Underground Cabins have their tiles and walls replaced with Rainbow Bricks, and a half of the remaining ones are painted with a diagonal rainbow pattern.
- Glowing Mushroom biomes are painted, with Giant Glowing Mushrooms painted in rainbow color and Mushroom grass painted in the same random color.
- Gem Trees are more common, similarly to the drunk world.
- All Floating Islands have Hallowed grass and a Hallowed Water Fountain.
- Some Boulders in Boulder traps are replaced with Bouncy Boulders or Life Crystal Boulders.
- Water pools near the Aether biome are replaced with Shimmer pools.
- The maximum number of Enchanted Sword Shrines is doubled, but the probability for one shrine to spawn is halved, except the first one which is guaranteed.
- The chances for a Lava Charm to be generated in a Chest is increased from 1/20 (5%) to 1/15 (6.67%).
- The chances for Water Walking Boots to be generated in a Chest is increased from 1/10 (10%) to 1/7 (14.29%).
Desert
- The Desert generates without its usual entrance but with a single Pyramid.
- The Chest in the Pyramid always contains a Pharaoh's set in addition to its normal loot.
- The caves of the Underground Desert are smaller.
Other changes
- Two unique enemies can be encountered in this seed:
- The Jungle Mimic can spawn in the Hardmode Underground Jungle.
- Golden Slimes can randomly spawn in place of a regular slime with a 1/180 (0.56%) chance.
- Fairies have a higher spawn rate in the Cavern layer.[3] All Fairies have a 5/6 (83.33%) chance to be a Pink Fairy.[4] The latter effect does not apply to Get fixed boi worlds.
- Mimics have a higher spawn rate.[5]
- When Hearts and Stars are dropped, they will randomly appear as normal variant or seasonal variant, with equal chance for each variant (1/3 (33.33%)).[6]
- All Fallen Star projectiles (including those from the Star Cannon, but not those from the Super Star Shooter) are pink.
- The chance for a Blood Moon to occur is raised to 1/6 (16.67%) (from 1/9 (11.11%)) per night.
- The chance for a Party to occur is raised to 1/7 (14.29%) (from 1/10 (10%)) per dawn.[7]
- The drop chance of the Rod of Discord is raised to 1/100 (1%) (from 1/500 (0.2%)).
- Fireflies and Butterflies are more common.[8]
- The chance of obtaining a developer set from a Treasure Bag is doubled, from 1/16 (6.25%) to 1/8 (12.5%). Developer sets can still only be dropped from Hardmode bosses' Treasure Bags (except Queen Slime's), however.[9]
- The chance for a Meteor Shower is increased from 1/10 (10%) to 1/5 (20%), and chance for a night to have an increased Fallen Star rate is increased from 1/3 (33.33%) to 1/2 (50%).[10]
- More clouds spawn in the background and more of them have a special shape.
- The move-in criteria for the starting NPCs (Steampunker, Princess, Party Girl, Town Bunny) are removed.[11] Should they be killed, they can respawn even if their conditions have not been fulfilled (e.g. the Steampunker can respawn even if no mechanical boss has been defeated). They do still require a vacant house in order to respawn, however.
- Every non-evil tree grows as a vanity tree, and all trees are painted in a rainbow pattern (including evil trees).
- Most bosses (including the Celestial Pillars and the bosses' minions, but except the Leeches, Servants of Cthulhu, King Slime, Queen Slime, Plantera, Golem, Betsy, Lunatic Cultist, and the Moon Lord) are smaller than normal.
- The Traveling Merchant always sells 2 more items than normal.
- The Princess sells rare items:
- Slime Staff
- Heart Lantern
- Flask of Party
- Sandstorm in a Bottle (while in the Desert)
- Terragrim (during a Blood Moon)
- Pirate Staff (after beating a Pirate Invasion in Hardmode, during the following moon phases:
) - Discount Card (after beating a Pirate Invasion in Hardmode, during the following moon phases:
) - Lucky Coin (after beating a Pirate Invasion in Hardmode, during the following moon phases:
) - Coin Gun (after beating a Pirate Invasion in Hardmode, during the following moon phases:
)
- The Wizard Hat grants an additional minion slot.
- The player explodes into confetti upon death, accompanied by one of the Don't Starve hurt sounds also heard in The Constant seed.
- Palm Trees drop 3 times as much wood on average (each tile of tree drops 2–4 corresponding wood).
- Sand, Hardened Sand, and Sandstone Blocks will always be painted cyan when placed.
While generating
- All generation descriptions and tips become pink.
- The Underground Hallow music will be played.
World icons
The world icon of a Celebrationmk10 world is a Pink Sakura tree with a bowknot.

Notes
- Due to the way certain invasion mechanics work, invasion events like Goblin Army will only take place near the initial beach spawn point. Unlike normal worlds, being near Town NPCs will not cause invasion enemies to spawn around the player.
- Goblin Scouts will spawn a third of the world away from the beach spawn, which means they spawn around the middle of the world and the opposite ocean.
Tips
- Starting with the spawn at the Ocean may make the early game progression much harder if the player is on the Jungle side. However, starting on the Jungle side makes it easier to find the Aether.
Trivia
- The names of the four non-pet starting NPCs in the Celebrationmk10 seed are the names of four members of Re-Logic: Redigit (Andrew), Cenx (Whitney), Yoraiz0r (Yorai), and Safeman (Amanda).
- Unlike most of the other secret seeds, the Celebrationmk10 seed is interpreted as a number, so any number of 0s can be added in the front (e.g.
000005162011). In addition, there are numerous unintended strings that generate this secret seed (due to the use of the CRC-32 algorithm[12]), such as (case-sensitive):
