On the night between April 2 and April 3, 2025, the wikis moved away from Fandom. Since then, we have had many successes…
- The Deltarune Wiki tripled in article count! From 204 pre-move, to 740 right now. Undertale Wiki is nearing 400 articles, from 318 pre-move.
- We had 3000 new users register since the move, not including temporary users.
- We had 66000 article edits! 14000 article edits to the Undertale Wiki, and 52000 article edits to Deltarune Wiki.
Here are some graphs breaking down these statistics per month, since the creation of the wikis.

April Fools
On Wednesday we had an amazing April Fools event. The wikis were full of FUN and on Deltarune Wiki you could see the Fun Gang themselves “fixing” the articles. Since April Fools is over, I wanted to share the details with users who couldn’t participate, and thank the people who helped us organize this.
Events
In the sidebar of the wiki, you could’ve seen a box showing your fun value, as well as a button to reroll it. Different fun values had different effects on the wiki, with some values only taking effect on specific pages. The fun values are no longer active, but you can enable the “April Fools 2026” gadget in your preferences to restore them! Conversely, if you liked the Cyber City and Cyber Field themes on Deltarune Wiki, you can enable them as well.
If you’d like to spoil yourself on what the fun values were, look here
Just like in Undertale, the fun value was rolled between 1 and 100, and different fun value ranges had different effects:
- 2-39: various terms on the page changed casing. This is a reference to Toby Fox and how he can’t choose one particular casing of words. Here are the terms:
- SAVE point, SAVE Point, SAVE POINT, Save Point, Save point, save point
- library, Library, Librarby
- surface, Surface
- Dark Fountain, DARK FOUNTAIN
- underground, UNDERGROUND
- Undertale, UNDERTALE, UnderTale
- Deltarune, DELTARUNE
- Sans, sans, SANS
- chapter, Chapter
- Weird Route, Snowgrave Route, Pipis Route
- 40-45: jack-o’-lanterns dance across the bottom of the page, like in Jackenstein’s battle
- 46-50: if you are on an item page on Deltarune Wiki, the Hammer of Justice appears to steal the infobox image
- 52, 77-81: various Lancer sounds play upon clicking on the page, and there is a 5% chance that a random image in the current view turns into Lancer
- 57-60: a crowd cheers from the bottom of the page, while words on the page get replaced with Tenna’s funnytext
- 61-62: mus_smile plays
- 63-64: a piece of Gaster appears in the bottom left corner. This entity is known as gastuh in the wiki’s Discord server.
- 65: Gaster’s Theme plays
- 66: the Mystery Man disappears from Gaster’s infobox
- 67: an excerpt from “friend inside me” plays
- 68: Asriel’s infobox image gets replaced by Togore
- 80-89: Pronouns from Kris’s infobox start falling down
- 90-96: Jackenstein’s pumpkin starts chasing the cursor
- 97-99: FRIEND appears
- 100: on the Sans, Sans/In Battle, and sans. pages, you can battle Sans
Congratulations to @Violetsquare111, @WitheredFreddy1993, @Joe_Art_Maker, @Ceruleanwarbler2 and @Cod10129 for winning the Sans battle while logged in! There may have been other users who won, but we couldn’t record them due to not being logged in.
Fun Gang edits
Our dear @Kris, @Susie and @Ralsei have been making edits for April Fools around the Deltarune Wiki, as well as posts in Discussions. While the edits have all unfortunately been reverted, here are some archives of them, and their art as well!
Archived edits
Special thanks
…to people who helped us organize this! In particular:
- @Link, who played Susie and a bit of Ralsei,
- @Ceruleanwarbler2, who played Ralsei in Discussions, edited as Susie, and drew Susie drawings for the Prophecy article,
- @Violetsquare111, who designed the Cyber Field and Cyber City themes, as well as Ralsei’s drawings,
- @Gil, for implementing the fun values for Gerson, jack-o’-lanterns, Lancer, Tenna’s funnytext, and the Sans battle ,
- and me, for the rest of the fun values.
Changelog
And for the end, here are some changes we made recently around Discussions:
- You can now add your pronouns to your profile, and they will display in your user card
- You can select the Cyber City, Cyber Field, 2nd Sanctuary and New Home color schemes in your interface preferences
- You can now upload audio files to Discussions (you can use this for sound effects, but please don’t upload big or copyrighted audio files)
- The Art category now properly shows thumbnails again
Happy wiki anniversary, and I hope the next year is even better.
