The other suggested changes come from the running dialogue Kermit has with George, Sweetums etc. regarding the backstage plot with the monsters.
So I thought I'd quote it and post the changed parts for easy comparison.

G: Kermit. I have a big complaint to make.
K: What is it George?
G: I am getting sick and tired of having to constantly clean up the mess that the monsters are always making in the canteen. It has got to stop.
K: Okay George. I promise to do something. (notices Sweetums nearby) Oh hey Sweetums. I want to speak to you.
S: Yes Kermit.
K: Listen Sweetums. George here is very unhappy about the way all the other monsters are making messes in the canteen. It must stop.
S: Well I'm sorry Kermit. But it's really in a monster's nature to be messy. They can't help being what they are.
K: Nevertheless Sweetums, they are going to have to learn to change their habits. (notices a what-not appearing in the background) Hey Charlie. Can you come here please?
C: Yes Mr.Frog?
K: Charlie I'd like you to go with Sweetums and give the other monsters instructions in good, clean, tidy habits. They've been messing up the canteen and causing poor George here extra work. I'll pay you for your troubles.
C: Okay Mr.Frog. I'll do it.
K: Thank you. You'll be sure to help Charlie with his task, won't you Sweetums?
S: Very well Kermit. But I'm telling you it's all just going to be a waste of time. (He and Charlie head off)
K: Are you happy with the action I've taken George?
G: Yeah. But it had better gain good results or else I'll downright refuse to clean up after those monsters anymore.
K: Listen Sweetums. George here is very unhappy about all the monsters making messes in the canteen.
S: I'm sorry Kermit. But it's a monster's nature to be messy.
K: There, are you happy, George?
G: Yeah. But it had better work or else I'll never clean up after those monsters again.
K: Well maybe they'll start eating up their own mess along with the rest of their meals.
G: That sounds promising. They should have enough appetite between them for that.
