I have a school SOON that wants a writing theme, so I'm thinking out loud here.

Professor's Nightmare: Importance of beginning, middle, and end is equal.
Kangaroo: Fun ways to write character descriptions.
Rewrite: Good Samaritan story told in cowboy form, then as a modern tale of a boy on a tricycle.
Magic Drawing Board: Let your words paint a picture of the character.
Genres: Different types of books (Library trick 1 and 2)
Captain Hook puppet: Different ways to hook the reader.
???

Got the best idea from my wife:

I will use the 4 color silk blendo with each color representing Who, What, When, and Where. These will be the outline for the program.
Who: Major and minor characters. I will do a skit with a major character from a story. Then I will do a skit where the ventriloquist figure roleplays a minor character in a popular story.
When: I will modernize the story of the Good Samaritan, using a boy who wrecks his bicycle.
Where: Space ship produces a character. This will let the kids know that there is no limit to WHERE the story can take place. They can make up their own planet!
What: Oh, That's Good, NO, that's bad skit will teach about trying to come up with surprise twists in the story.

Plus, the things I mentioned above, but placed into categories of who, what, when, and where.

Should be fun! And I don't have to write any new skits, just oganize some from different shows to fit the theme!

Tony, this is an excellent structure. What grades will you be presenting it for?

Therein lies the ?
It is two back to back assemblies, ranging from K to 8th grade. The majority will be elementary.
I plan to pack the car now and will make the final plans as I pack. (No worries, mate.) But I think I'll toss in several just in case stories. Ex. Balloons where I call kids up and turn them into a tree, elephant, monkey, with balloons.

Color silks who, what, when, where
WHO:
1. Major character Kangaroo skit (facts about the character-funny)
2. Minor character Shepherd + sheepdog at Christmas
3. MDB: Paint your character with words. Pick one memorable visual fact. (moustache, hat, pink glasses, or etc.)
4. First person or third person. Interview with mic mouth?

WHAT:
What happens? Think like a roller coaster. Twists and turns, surprises, dark and unknown, fast action, but all headed toward the ending.
5. Story of Namar the elephant with balloons.
6. Focus on the senses: Describe a battle between Peter Pan and Captain Hook as seen by a. a deaf person (tells what he saw)
b. A blind person (tells what she heard)
Also mention touch and smell items in the story.
7. Professors Nightmare: Beginning, Middle, and End are all important

WHEN:
Pick a time zone. Castles? Caves? Futuristic? Westerns?
8. Tell a modern version of the Good Samaritan

WHERE:
9. Spaceship. You can put your story anywhere!

Odds and ends if time:
10. Bookworm trick from Samuel Patrick Smith: Different genres.
11. Giant eraser or appearing pencil (talk about rewrites)

Ending 12. Review with the 4 color silks into the silk blendo.

Did the show for K-3, then 4th-6th graders today. Changed very little from what I put above and it went very well. All of the stories I used as demos were Bible based, as it was a Christian school. But I think I may write a couple of skits and turn it into a library show. I could go with a space theme and call it, "The Write Stuff", but I doubt if many people know the reference.

Booked my first library with the new writing show.

Congrats Tony on your booking.
I wish you luck.
