It was requested that I do Bill and Flowey as pals (or not) (they're not) and then that I draw Bill, Flowey and Herobrine all together.

So, Bill and Flowey and Herobrine.

F: "I swear, if you call me 'flower boy' ONE MORE TIME, you flying dorito..."
B: "You know, I've always wondered if sentient plants burn as well as normal ones!"
H: "I'm... honestly not sure if I should be concerned about this, amused by this, or concerned about how much I'm amused by this..."

So yeah. Bill and Flowey would get into a fight, while Herobrine would question his standards.
