Despite the warnings, there is a reason this keyword is gaining traction. The Undertale community is starved for official content. With Deltarune Chapters 3 & 4 on the horizon, fans are filling the gap with any mystery they can find.
QuackPrep.org offers a specific flavor of mystery that the fandom loves:
One Twitter user (@UndertaleSleuth) posted last week: "I don't know what QuackPrep is, but the 'new' build has a fight against 'The Feathered Knight' and he talks about the 'Save file of the Duck.' This feels too polished to be fake."

The site looks like a broken test prep service. Think generic SAT flashcards, ugly Comic Sans MS layouts, and placeholder images of ducks wearing graduation caps. Boring, right?
Except for the source code.
