The first set of names the SOUL is bombarded with.

Upon completing a True Pacifist Route, a credits sequence featuring all of the monsters of the game occurs, followed by a bullet-hell segment in which the names of the Undertale Kickstarter backers may be dodged.

If the protagonist dodges all of the names, the Mysterious Door in Snowdin Forest unlocks.

The description of each monster is either white or yellow depending on what the protagonist did during their encounter.

Trivia

  • Jerry, Chilldrake, Glyde, So Sorry, enemies exclusive to Hard Mode, and the mysterious white figure in the True Lab do not appear in the credits.
  • In the Special Thanks segment of the credits, Toby Fox is included in the names.[1]
  • The beach Alphys and Undyne visit resembles the beach in Summers from EarthBound.
  • Gyftrot's white and yellow descriptions are possibly reversed, since the white description can seem like a better rate than the yellow one. 
  • Some of the monsters' sprites change depending on whether they have white or yellow credits. For instance, Shyren only shows her face if she has yellow text, Lesser Dog's neck grows if its text is yellow and Aaron's facial expression changes.

Notes

  1. Mad Mew Mew is only available on the Nintendo Switch version and she only shows up in the credits if the player fought her, replacing Mad Dummy in the process.
  2. 2.0 2.1 Muffet and the Royal Guards will always have yellow descriptions, as the credits cannot be reached without fulfilling their yellow description conditions.
