Deltarune Chapter 5’s secret boss is being described as very hard , with some players calling it the toughest fight in the game so far, though opinions vary on whether it’s harder than the final boss.

What people are saying

  • One recent guide says Chapter 5’s secret boss is Pink, also called Mad Mew Mew, and includes a full beat-the-boss walkthrough.
  • Player discussion suggests the fight has chaotic attack patterns and may force heavy item use or very tight dodging.
  • Another guide frames it as a standard secret-boss challenge with unlock steps like collecting Pink Coins and reaching the Pink Door.

Practical read

If you mean “hard” in the usual secret-boss sense, the answer is yes, pretty hard.

If you’re asking whether it’s unfairly impossible, the community reaction looks more like “demanding but learnable” than “broken.”

Unlock difficulty

The fight also sounds annoying to reach, not just to clear, because you need to gather the required Pink Coins and key-related steps first.

Bottom line

Expect a tough, pattern-heavy boss with a steep learning curve, especially if you’re going in blind.
