Robin had been feeling unaccountably melancholy all day yesterday, and today, he simply didn't move. Pepe and Anastasia decided to leave him be for now, but tomorrow they would do everything in their Muppety power to get him out of whatever mood had siezed him.
But right now, Robin didn't move, or speak. He just lay limply in bed staring at nothing.
[Jerry Nelson, the original performer of, among other Muppets, our own dear Robin, passed away yesterday at the age of 78. We'll miss you Jerry. Thank you, and goodbye.]
