Snas in da haous is a unique FNF mod that brings the beloved Undertale character Sans (spelled "Snas" for humorous effect) into the rhythm arena. Created by a fan developer, this mod combines custom sprite work, multiple music sources, and a lighthearted tone.
All Snas sprites were made by the mod author, giving the character a distinctive look while staying true to Sans's lazy but menacing charm. The game engine was developed by Meekaryo, providing a stable Scratch-based framework. Music comes from two sources: the main FNF song was composed by Samuel Wolfang (check his Twitter), while other songs are original Undertale tracks by Toby Fox. The mod is tagged #fnf #sans #fridaynightfunkin for easy discovery.
Start by pressing the green flag, then click the Play button. To skip dialogue (if any), simply press any key – the developer jokes "break your keyboard to skip dialogue". After that, the standard arrow key mechanics take over: press the matching arrow when it reaches the target zone. The current version is 1.6v.

The mod runs on Scratch, so it works directly in your browser without installation. The developer has kept the instructions minimal, assuming players already know the rhythm mechanics. There is no complex configuration – just pure arrow-based gameplay with a Sans twist.
