He was for Rotisserune, specifically a route of Chapter 2 where you're with Muppet Cory and you have to go through the outskirts of the city

His fight was like Mettaton's but backwards
You had to do cutesy stuff like strike cute little poses and hug Muppet Cory and all that
To f**k up the ratings and make nobody wanna watch it
I don't have dialogue written but Mr. Lively K pretty much says "All my viewers are gone. I would kill you for that, but I wouldn't get anything out of it, so I'll just leave."
