Usually they say something in character so it really varies. Like, Pooh is gonna go on a honey break. Or Mushu has to go meet with the Emporer. Stuff like that. My advice would be to think about the character and then think about something that would logically fit that character.
Exactly.
Here's a few other examples:
-"Brer Rabbit is going back to his briar patch."
-"Robin Hood needs to return to Sherwood Forest."
-"Jiminy Cricket has to go see the Blue Fairy."
-"Tigger is going to grab a quick piece of birthday cake."
-"Minnie needs to power her nose."
-"Goofy is going to check on Max's homework."
-"Chip & Dale are going to get some acorns."
-"Scrooge McDuck has to go count his cash."
-"Lilo has to get to her hula class."
-"Pocahontas has to go meet John Smith."
-"The Queen of Hearts is going to check on her roses."
-"Baloo has to go back to the jungle."
-"Carl Fredrickson, Dug & Russell are going to check on their balloons."
-"The Country Bears need to go get ready for their show."
Similar things are done when a CM has to mention that a particular is not making appearances on a particular day. For example:
-"The 7 Dwarfs are busy working in their Daimond Mine."
-"Prince Eric is giving his dog Max a bath."
-"Shang is off fighting some Huns."
-"Jose Carioca had to go to a samba lesson."
-"Panchito is at a fiesta."
-"The 3 Little Pigs are busy rebuilding their houses again. The Big Bad Wolf won't stop blowing them down."
Just to give some ideas.
