Despite us absolutely adoring Blueberror we don't typically draw them often, much less horny. So took the time recently to rectify that.

Lala, my yandere little blue ring bitty!
Me and my lovely partner @luckypies.bsky.social have vaguely(?) decided that the owner would be Blueberror.
....But only after I had doodled this
He WILL try to kill any of the people BB brings around

My AP group shuffles in a big 250 piece puzzle for players that get stuck, and so that spectators can join in in some way.
Last time one of our members @blueberror-sans.bsky.social drew the puzzle art featuring the MC's from everyones game

I noticed people drawing dream sans dying violently after he lost the polls, I thought this was pretty funny

I have to say... while I'm pleasantly surprised by some of the lineup of this year's Sans AU Sexyman Poll (Paper Crane & Blueberror🥹), I still have NO clue why tf Snas is included. I love Underpants, but it's not an AU, it's a parody series, and I don't think anyone is thirsting for Snas.

It's such a lazy way to fill a space that could've been given to a lesser known AU that could've used the exposure. I'm not super happy with how unfairly matched some of them are either. Obviously everyone's gonna vote for Error over Blueberror, his counterpart who's story never even got to happen.

I love Wine, but I just had to vote for Paper Crane, the underdog. I voted for Blueberror too. I don't care that it probably wasn't worth it. It made me sad knowing they were getting demolished by their opponents. Maybe if it were Razz I would've voted for him.

Blueberror was a Swap!Sans that was taken into the anti-void, becoming an error himself. :')
