Okay, both Undertale and Homestuck have a particular Vocaloid song that people like to use with it. Homestuck has Matryoshka. Undertale, on the other hand, has Drop Pop Candy. So now I give you the Jubyphonic cover and the Undertale cover being sung (almost) at the same time. The timing's slightly off so don't mind. The singers are Juby, Kuraiinu, Sans, and Papyrus!
