April 2017: a commission for a riff on the previous sans blaster pic: make it Underfell!

Happy monday saturday everyone #underfell

February 2016: The other side of "How to Tain Your Underfell", where Blue goes to Underfell and... well... reenacts my favorite "Tangled" song. 1/4

3/3 Meanwhile, in Underfell... (Yes it's a steven universe parody)

February 2016: "How to Train Your Underfell" Honeymustard part 2! 1/3

February 2016: I made a small unfinished series of drawings that I dubbed "How to Train your Underfell". (These are still up on my BluecrystoArt tumblr.) The plot was pretty much that Red(UF Sans) and Blue(US Sans) swapped universes, and the chaos therein. Part 1: Honeymustard

March 2016: Red underfell showing his teeth! Sometimes you just wanna draw quick vent art. >:3

January 2016: I still adore a tsundere Underfell Sans to this day, and Honeymustard used to be one of the biggest ships in the fandom for a few years before UTMV took off. I love how bottom-heavy he looks in this pic, hee. <3
