He likes big snouts.
Following news of his breakup with Miss Piggy, Kermit the Frog has already rebounded to a new pig named Denise. All this drama is leading up to the new Muppets sitcom, which will be a documentary-style show portraying behind-the-scenes production of "Up Late With Miss Piggy" (similar to 30 Rock). This should make things awkward at work, because Denise is a marketing executive at ABC, which is the network producing Miss Piggy's show.
Rookie mistakes, Kermit! You should avoid dating coworkers, and you definitely should not date multiple people at the office. Once you end a long-term relationship, you're supposed to get out there and spice things up! Maybe get weird with a female version of Gonzo or Animal. All sorts of exotic creatures in the Muppet family.
Kermit is trying to keep a low profile, which is wise because either he or Denise are going to walk away from this with severe injuries. Or they may not be able to walk at all. Let's not forget that Miss Piggy would straight up punch Kermit in the face for making a joke at her expense. If Denise knows what's good for her, she'll move, change her number and delete all her social media accounts. Hell hath no fury like a pig scorned.
