The time of the day is always night, and it never turns a day.The Terraria logo spins out and disappears along with the version number.The Console Title music plays, instead of the normal Title Screen music.The outline of the progress bar rapidly flashes between Corruption and Crimson.Once the world finishes generating, it is possible to go back to the main menu with these effects still visible. The moon moves backward and resembles a smiley face (see Trivia). The background shows a Glowing Mushroom biome, with clouds that resemble Redigit's head.Generation descriptions and tips become random numbers that change every tick (except when ' Placing traps').The Party Girl replaces the Guide as the starting NPC, and the Dungeon entrance is now generated under a Living Tree painted brown.

In this seed, both Evil biomes will generate, as well as both variants of any ore that comes in two varieties. It has therefore come to be referred to by the Terraria community as drunk world. It invokes a highly extraordinary world generation referred to in the source code as drunkWorldGen. This seed references May 16, 2020, which is Terraria's 9th birthday and the release date of 1.4.0.1.
