What’s more fun than taking advantage of your new friend that isn’t affected by your singing charm than using his back as a resting spot while you advertise both of your bands in the form of singing and a sign? Well, mostly yourself, and the sign is painted with his blood, so you should probably not make him too mad, lest he kick you in the balls that he doesn’t even think you have.
 
What you can’t see out of frame is random ponies under a spell and following.
 
_{^{Also that sign better be readable, I spent too long on it.}}
