Pink fight from Deltarune Chapter 5
How to play
- Press Play. The battle starts on its own. There is no second green flag.
- Click the battle once. Until that click, the keys do nothing.
- Arrow keys move the red heart and move through the menu.
- Z confirms. X goes back.
A phone cannot play this. The menu is FIGHT, ACT, ITEM, and MERCY. Filling the DOKI meter does not start a date in this version.
Press Play, then click the battle. Arrows move the SOUL and the menus, Z confirms, and X steps back. This is the first combat phase only.
What this build actually plays
Open the frame and the party is already in the menu: Kris, Susie, and Ralsei, with FIGHT, ACT, ITEM, and MERCY under a DOKI meter. The_Fish909's notes say V0.1, dated 10 June 2026, was the first combat phase with no dating and no dialogue. Later notes do not claim those missing pieces shipped.
The author writes that the battle is based on DELTARUNE by Toby Fox, that Temmie Chang drew the art, and that Toby Fox wrote the music. The TP bar is credited to The_CommanderRS and Grishagames. On 22 October 2026 the Scratch page showed about 9,794 views, 285 loves, 283 favorites, and 17 remixes.
How far the DOKI meter goes
Pink's fight in Chapter 5 is not won by emptying an HP bar the way a normal boss is. The party flirts, the DOKI meter fills, and later stretches of the official battle split into dating scenes. This Scratch build stops before that. The description says, in the author's words, that nothing happens when DOKI maxes.
- V0.1, 10 June 2026: first phase only. No dating, no dialogue.
- V0.2, 14 October 2026: Kris softlock fixed, infinite-item bug fixed, side DOKI bar added, Giga Flirt fixed, hitbox shrunk. Dating was only started, not finished.
- V0.2.1, 15 October 2026: small health-bar tweaks. That is the build packaged here.
If the meter fills and the battle just sits there, that matches the author's own note. It is not a missed key. The Chapter 3 Knight and Gerson are finished enough to practise a whole opening. This one is not.
Pink, not Flowery
Chapter 5, Festival Day, came out on 24 June 2026. Its chapter boss is Flowery, in Flower Kingdom, and the new movement there is the orange SOUL dash. Pink is the Shadow Crystal boss of the same chapter. Players also search that fight under Mad Mew Mew, because Pink is Deltarune's counterpart to that Undertale character.
This page does not include Flowery, the orange dash, or the dating scenes. For a different secret boss that is further along, open Jevil or Spamton NEO. For the knight people are already practising, open the Chapter 3 Knight.
FAQ
Is this the pink fight from Deltarune Chapter 5?
It is a fan battle of Pink, the Chapter 5 Shadow Crystal boss, not the official game. DELTARUNE is Toby Fox's game at deltarune.com. This page plays The_Fish909's Scratch project 1351806297, shared 11 July 2026 and last updated 15 October 2026 as V0.2.1.
What do the keys do in the pink fight?
The author's instructions say arrows move and use the menus, Z selects, and X goes back. Press Play, then click the frame. Until that click, the keys do nothing. A phone has no touch layout for this battle.
Does a full DOKI meter start the date?
Not in this build. The project description says nothing happens when DOKI maxes, and that dating and extra phases are still being made. V0.2 on 14 October 2026 added a side DOKI bar, fixed a Kris softlock and an infinite-item bug, and made Giga Flirt work. V0.2.1 on 15 October 2026 only tweaked the health bar.
When does the browser request the packaged battle?
Until Play, the frame holds a poster and does not contact gamebox.bvnplay.online. Pressing Play downloads the package. A school or office filter can still block deltarunefight.com or that game host.
Is Pink the same boss as Flowery?
No. Flowery is the Chapter 5 chapter boss in Flower Kingdom. Pink is the optional Shadow Crystal boss of that chapter, the Deltarune counterpart players also call Mad Mew Mew. This page is only the Pink battle.
