The Muppets appear throughout the show's fourth season (branded as Holey Moley: Fore-Ever), which premiered on May 3, 2022. In the season premiere, Rob Riggle recruits Kermit the Frog and company to help ensure that the series will get renewed for another season amid (fictional) budget cuts. This results in planning a big production number finale and Pepe the King Prawn kidnapping Stephen Curry.
The Muppet cast for the season includes Kermit, Miss Piggy, Fozzie Bear, Pepe, Animal, the Swedish Chef, Statler and Waldorf, Lew Zealand, Camilla the Chicken, Sam the Eagle, Bobo the Bear, and Joe the Legal Weasel.
A teaser video for the season featured a vocal cameo from Kermit the Frog, yelling "Fore!" as a golf ball baring his likeness crashes into the screen.
