~Purr purr~  
I don’t think ponies can purr, but he’s a siren, so I say he can.
 
So this was pretty fun to make, took awhile, and I had to focus on ‘less is more’ so there’s only six breathing frames, plus three ear flick frames, and three blinking frames, 26 total, if we count duplicates.
 
He’s sleeping on a bed, because transparent backgrounds in GIFs look bad. Don’t tell me to use WEBMs, please.
 
Also sleeping siren, hurrdurr.
 
Blink and ear twitch.
