Because "Quack Prep" is not an official canonical term, this write-up will cover the most likely subject: the Super Smashed Bros Trophies/Social-Networked Dummies, the "Quack" (Pipis) enemies, and the humorous community interpretation of "preparing for a quack."
Here is a detailed write-up on the subject.
Data miners have identified an internal game flag called egg_prep_quack. According to this theory, Chapter 4—which takes place in a "Living Room" Dark World—will feature a prep school-themed library. The secret boss is a sentient, disembodied duck head wearing an ascot. This boss, Mr. Quack Prep, forces you to answer trigonometry questions. If you fail, he quacks so loudly that your party’s MP resets to zero.
Here are the three dominant theories explaining quack prep deltarune.
As of now, quack prep deltarune exists only as a collective hallucination of a very bored, very creative fandom. There is no official confirmation from Toby Fox. The "QUACK_PREP_PREVIEW.wav" was a hoax. The data mine flags are likely placeholders.
However, in the world of Deltarune, nothing is truly fake. The game is built on secrets. If you search hard enough in the files of Chapter 1, you will find a single text string left by the developers: * The duck prepares for its exam.
So keep your eyes open. When Deltarune Chapters 3 & 4 finally release, pay attention to the background of the Light World. Look for the rubber duck. Listen for the quack.
Because when the quack prep deltarune finally arrives, we will all be prepared.

Title: Quirky, Quacky, and Surprisingly Dark – A Quack Prep Deltarune Review
Rating: 4.5/5 rubber duckies 🦆 Theory 1: The Secret Boss of Chapter 4
Quack Prep Deltarune is the kind of fan game that shouldn’t work on paper but absolutely nails it in execution. Taking the wacky premise of a “prep school for ducks” and transplanting it into the Deltarune universe, this Chapter 2.5 fan adventure delivers humor, heart, and one surprisingly unsettling villain.
The Good:
The Mixed:
The Bad:
Verdict: If you loved Deltarune’s blend of charm and menace, Quack Prep is a must-play. Just don’t skip the dialogue – the ducks have secrets.
🦆 Final quack: “Highly recommended, 10/10 waddles.”
Some theorists believe "Quack Prep" is a nickname for a minor character who attended the same prep school as Dess Holiday (Noelle’s missing sister). In this dark timeline, Dess was teased by a group of duck-themed prep students. The quack represents the mocking laughter. When Noelle finally finds Dess in Chapter 5, she will have to confront the "Quack Prep" gang. This plays into Deltarune’s themes of bullying and trauma.
In the Deltarune community, the term "Quack Prep" is an informal, meme-centric phrase usually referring to one of two things:
Most commonly, fans use "Quack Prep" to describe the chaotic, item-heavy preparation players undergo to survive the "Pipis" (Quack) attacks during the Spamton NEO boss fight.
