"Dummy! (Beta Mix) - Undertale" is a high quality rip of the beta mix of "Dummy!" from the game Undertale.
In this rip, the advertised track is played along with samples of Loud Nigra roughly pitch-shifted to the tune of the original song. The pitch shifting is not very well done, especially compared to later rips; while it was originally uploaded on GiIvaSunner, it wasn't reuploaded to SiIvaGunner until the Nostalgia Critic takeover, where numerous other rips were uploaded.
