Kermit the Frog | Kermit the Pig is a green pig with features similar to Kermit the Frog's, including a collar and ping pong ball eyes. Kermit the Pig takes over as the show's MC, and claims to be a frog. When guest star Cloris Leachman doesn't believe him, he ribbits for her convincingly. His cheer of "Aaaahhh!" is a knockoff of Kermit's "Yaaaay!" |

Sweetums | A pig named Sweetums replaced Sweetums. The puppet was recycled from the Ballerina Pig (albeit dressed in furs). |
 Performer: Jerry Nelson |
Fozzie Bear | Fozzie Pig (also refered to as "Fozzie the Pig" by Gonzo) is a pig with a porkpie hat and a pink, polka-dotted bow-tie. The pig replaces Fozzie Bear as the show's comedian. In contrast with Fozzie Bear's well-established "Hiya hiya," Fozzie Pig says "hogga hogga." |
 Performer: Frank Oz |
The Swedish Chef | A pig chef replaced the Swedish Chef in a skit where he prepared popcorn. In contrast with Swedish Chef's signature catchphrase, "bork, bork," the pig chef says "oink, oink."
The Swedish Chef returned the favor by impersonating a pig in Muppet Treasure Island. |
 Performer: Richard Hunt |
Dr. Bob | Doctor Pig replaces Doctor Bob in the Veterinarian's Hospital sketch. Dubbed the "Vegetarian's Hospital," he was assisted by Nurse Piggy and another pig. |

The Newsman | A pig replaces the Newsman in a Muppet News Flash sketch. In his report, he mentions a Dr. Bunsen Honeypig, who was said to have successfully converted a sow's ear into a silk purse and became the object of a massive civil and criminal suit by the wife of Vincent van Gogh Pig. |
