Deltarune Chapter 5 Weird Route: Side B Steps and Failure

Start Chapter 5 Weird Route from a Chapter 4 completion file, finish the timed lake sequence for Side B, or learn what changes when the route is aborted.

Direct answer

Chapter 5's Weird Route requires a completion file that continued the route through Chapter 4. At the chapter start, repeatedly press movement inputs to force Kris out of bed, get Bread from Sans's ice cream stand, go to the lake, and complete Noelle's increasingly fast choice sequence. Success ends the chapter early at the "Insert Chapter 7 Side B" screen.

If the timed prompts expire, the route is aborted. Chapter 5 continues into Flower Kingdom with altered scenes, and the normal Dark World content, Pink Door and secret boss remain reachable.

Side B steps

▸Load a Chapter 4 completion file that continued the Weird Route.
▸At the start of Chapter 5, repeatedly press movement inputs until Kris gets out of bed.
▸Leave home with Susie and speak to Sans at the ice cream stand outside his store to obtain Bread.
▸Go to the lake. Once you enter the lake area, you cannot leave.
▸Advance through Noelle's first 13 choice prompts. Early Stop and Proceed choices do not prevent the sequence from continuing.
▸After Kris and Noelle are submerged, answer the next 60 prompts quickly. Each answer resets a timer that becomes shorter as the sequence continues.
▸Complete the sequence to reach the CRT ending and create the Side B completion file.

Success vs abort

Result	Trigger	Outcome	Access
Side B completed	Finish all timed lake prompts	Chapter 5 ends immediately, creates a special completion file, and skips Flower Kingdom and Chapter 5 SAVE points.	No Pink boss, Chapter 5 Shadow Crystal, Egg, or normal Dark World exploration on that completion.
Route aborted	Let the lake prompt timer expire	The story returns to the main Chapter 5 structure with altered Light World and Dark World scenes.	Flower Kingdom, Pink Coins, MysteryKey, Pink, Egg, and Shadow Crystal content remain available.
Normal route	Load a completion file without the Chapter 4 Weird Route state	The special lake sequence does not become the Side B route.	Normal Chapter 5 content is available.

Before choosing the ending

▸Use a separate completion file if you want to see Side B without losing access to Chapter 5 exploration on your main branch.
▸Complete Side B if your priority is preserving the Weird Route continuation toward Chapter 7.
▸Abort the lake sequence if your priority is exploring Flower Kingdom and collecting Chapter 5 secrets.
▸Do not complete Side B on the only file you intended to use for Pink's Shadow Crystal.
▸For TwistedSwd planning, remember that PureCrystal remains unobtainable and the Chapter 5 secret boss crystal is skipped by Side B.
