Identify digital instrument or origin of samples used in "Temmie" music in "Undertale" game

Question

Where do the vocal sounds in the "Temmie Village" music track of the video game "Undertale" stem from?

Video with music: http://youtube.com/watch?v=yOD8ZZ8RTic

Can you identify whether they are from virtual instruments (which VSTs?) or are these samples, for example from VOCALOID (which voices?) or are they auto-tuned own recordings?

Thanks!

Answer 1

The Temmie voices are made with the Mixcraft Instrument Preset “Boy Band”.

You can hear the instrument in action in this video.

Answer 2

They're just normal vocal samples, likely recorded by Toby Fox himself or taken from some SNES game or sample library. They do not use any extra processing. (ex. vocoder, auto-tune)
