Unlike massive streamers who treat Undertale as a one-off nostalgia trip, QuackPrep dives into the code, the dialogue trees, and the emotional weight of Toby Fox’s masterpiece.
Their Undertale content is unique because it is rarely just a "first playthrough." QuackPrep approaches the game with a meta-knowledge that evolves over time.

Instead, “Quackprep” is a folkloric internet handle—most likely the username of a now-obscure content creator from the mid-to-late 2010s. As a result, what remains is fragmented
Based on archived forum posts (from Reddit’s r/Undertale, deleted Tumblr threads, and YouTube comments), a user named Quackprep or QuackPrep was active in the Undertale fan community around 2016–2018. Their claim to fame was a series of unedited, “full” game playthroughs, often with specific constraints: no commentary, no deaths, “true pacifist” runs, or, conversely, “genocide speedruns” with developer commentary disabled.
However, the phrase “Quackprep Undertale Full” gained a secondary, more mythical meaning. Quackprep was rumored to have uploaded a complete, uncut, 6+ hour video of Undertale that contained anomalous glitches—things that shouldn’t exist in the base game. Viewers claimed to see:
