A video explaining why I use Patreon and why I'd so massively appreciate it if you'd like to contribute:    • My Last Ever Video? UNDERLAB  

We all know Sans has one or two jobs... or maybe three. Here's a video on the secret job Sans works that he'll never directly tell you about, but it accounts for all his mysterious behaviour in-game. It also quite likely fills in his backstory in places where there were gaps before, clearing up Sans' connection to Gaster, the true laboratory and various other things. It's time to find out Sans' secret backstory!

The Secret Power You Never Knew Sans Had! Undertale Theory:    • The Secret Power You Never Knew Sans ...  

Underlab explores the secrets and obscurities of UNDERTALE, that game everyone seems obsessed with. There's a lot of said secrets and obscurities. Like, a lot. It also showcases and explains the lore and story of the game in an attempt to explain, clarify, and perhaps even discover completely new stuff...
