Sorry for the trouble, y'all! Take along this key...
Yellow, Chapter 5
The YellowKey (JP: イエローキー Ierō Kī) is a Key Item in Chapter 5 of Deltarune.
The YellowKey is acquired in Flower Castle after defeating Yellow's bullet pattern and convincing him that he trampled Blue's flowers. It is used to open the Yellow Door in the west wing of the castle. The room inside is revealed to be the start of "THE WAY THAT PUNISHES YOU (BAD WAY)", prompting Susie and Ralsei to find Yellow.
When the YellowKey is used, the narration states "The Yellow Key got used up", referencing the similar narration when the Ice Key is used in Chapter 3.
