Deltarune Chapter 5 Guide: Surviving The Lake Sequence And The Weird Route
Attempting the darkest path in the new chapter requires carrying over specific save data and fighting the game's attempts to stop your progress.
Toby Fox completely derailed the narrative structure in Chapter 5. Following the standard path lets you enjoy a town festival with Susie before entering the flower shop Dark World. Taking the Weird Route skips the Dark World entirely and traps you in a disturbing sequence where you march into a lake to drown alongside Noelle. It is a sharp tonal shift that fundamentally breaks the normal flow of the game.
Because this path avoids the Dark World entirely, you're locked out of all optional encounters and hidden collectibles. If you want to hunt down currency or fight the secret boss, you have to load a standard save file instead.
Setting Up The Lake Sequence
You can't just wake up and decide to take the evil path. This route demands a precise setup based on your previous decisions, and the game actively fights your inputs from the moment you start.
The Save File: You must load a file where you successfully finished the Chapter 4 Weird Route.
Waking Up: When Toriel speaks, mash the directional inputs to force Kris out of bed. The controls feel incredibly heavy here, and Kris moves at a crawl. All dialogue boxes not spoken by another character appear completely blank, and you sleep right through the festival.
Acquiring The Bread: Walk to the grocery store with Susie and speak to Sans to grab the Bread. This step is mandatory. Securing this item is the only way to bypass Susie's dialogue triggers, otherwise she stops you to talk about Noelle wanting ice cream. The Bread's description notes that it leaves a trail, hinting this is the exact same Sans from Undertale collecting breadcrumbs for his hidden workshop.
Ditching Susie: Head to the lake and confirm the prompt to have Susie leave Kris alone.
The Proceed Sequence
Once you enter the lake area, Noelle delivers a chilling monologue about breaking her routine. You receive eight different dialogue prompts during this speech. It doesn't actually matter if you pick "Stop" or "Proceed" here, though the game secretly tracks your resistance. If you tell her to stop, Noelle forces the progression anyway. She's fully in control.
The two of you hold hands and walk directly into the water. As you submerge, the screen shakes violently, the textbox borders turn red, and Noelle's portrait distorts.
This initiates a hidden timer minigame. You'll be spammed with roughly 70 choice prompts, and you have to select "Proceed" every single time before the clock runs out. Every click resets the timer, but the window shrinks from eight seconds down to a single second. Hovering your cursor over the exact spawn point of the prompt is mandatory, as the audio static and visual distortion make reading the screen impossible in the final moments.
Surviving The Timer And Failure States
If you miss a prompt or intentionally let the timer expire, the screen whites out. Noelle states that Kris hasn't changed after all.
Failing doesn't kick you to a standard game over screen. Instead, the game dumps you straight into the normal Dark World route, skipping the light world intro segment. Characters acknowledge the shift with slightly different dialogue, and the code triggers a unique flag. This means if you miss a single input, you have to reload your save file from the absolute beginning to try again. It's a clever failsafe that punishes hesitation by forcing you back onto the exact path Noelle was trying to escape.
Side B And Skipping Chapter 6
If you successfully mash "Proceed" through all 70 prompts, the screen cuts to black. A retro CRT monitor appears with a single instruction telling you to "Insert Chapter 7 Side B."
The game boots you back to the file select screen, and your save file gets a "_B" appended to the end of it. Because there are zero save points in this version of Chapter 5, this is the definitive end of the route. You broke the narrative so thoroughly that you skipped Chapter 6 entirely.
This confirms the theory that the Weird Route isn't just about making evil choices. It's a meta-narrative about breaking the prophecy and escaping the intended sequence of the game. Noelle realizes she's trapped on a set path and decides drowning is better than following the script. Pushing past the limits of drowning sets up a completely unpredictable scenario for Chapter 7.
