I have a confession. I think Scooter's role in the Muppet Movie was awkward and felt forced.
With everyone else that joined Kermit, they had a great moment and scene unique to them, and most got their own musical number.
- Fozzie: He bonded with Kermit st the El Sleazo and had Movin Right Along
- Piggy: Great scenes with Kermit at the fair and the restaurant, and Never Before, Never Again
- Electric Mayhem: Scene at the church gave them a great feature, plus them breaking the 4th wall and coming back was clever, and Can You Picture That?
- Rowlf: I Loved his scene at the piano, and I Hope That Something Better Comes Along was an instant classic
- Bunsen and Beaker: While they didn't get a song, they were featured prominently and their invention (along with Animal's lack of supervision) saved the day
Then there's Scooter. He gets no scene that's just about him. He doesn't even get to speak directly to Kermit at all. He's just tacked on to the Electric Mayhem as an afterthought, and he's never been paired with them before or since.
For someone who was Kermit's right hand man and was a very prominent character on The Muppet Show, I think he could've been given a better scene.
