According to Muppet Wiki, the new penguin's name is Gloria Estefan the Penguin. Not sure how I feel about the character being named this, but could open up some humor if Gloria Estefan is ever a guest star on the show.
Reading the description for the next episode, I get a feeling that the new head of the network will be a one-time character. I guess we'll have to wait and see. Of course I never thought he'd be in every episode (like how Becky isn't in every episode). Would it be a step back if instead of this new guy they suddenly had J.P. Grosse owning the station?
