Well, since you guys want Gallus so bad-- and mind you, I do too-- here's the blue bird himself! With a little help from a lesser-known friend of his...
This is a surprisingly wholesome(?) scene: Sun is feeding Gallus into blobdom so that he can charm Sandbar, whom is with Yona but certainly open to being with Gallus too. What inspired this strategy to win the earth pony's heart? ...I... legitimately don't know. I think Sun might be a freak. Or just insane. Honestly probably the latter.

One random thing I wanted to mention quickly: in the fic Sun is from, Songs of Innocence, there's a chapter dedicated to Sun and her friends having a surprisingly intense food fight against the Student Six (think "Best Day Ever" from RWBY). I was considering making this depicting Sun defeating Gallus in another food fight by stuffing him. Obviously that wasn't what I ended up drawing, but I like this route I went with. Hopefully you do too, and I've done this blubbery birb right by you all!
