Ohh, there is plenty of room left!
I'm just saying the minimum is 10 people, 5 per side.
I originally wanted 4 from each clan and the strawberry and chocolate hokage.
The clans would in fact be:
Chocolate 4, 1 hokage (me)
Dark Chocolate 3-4 (ally)
Almond Crunch 3-4 (ally)
Strawberry 4, 1 hokage
Green Tea 3-4 (ally)
Bananna Dessert 3-4 (ally)
That would be 25 total spots if we could do the full thing and each battle lasted less than a minute, which they should.
If we only had 10 total and still had time we would just have the dead ones sneak backstage and change headbands and swords to the next clan.
If time isn't on our side then I would only have 10 and each hokage would send one ninja at a time.
either 4 chocolate/strawberry, or 3, one from each clan and ally to fight, and then the two hokage duel.
I've also thought of two other endings to poke around with.
1. just the chocolate and strawberry go to war and suddenly the Jolly Green Tea Giant appears with the biggest Pocky of all and slays all the ninja, a twist that Green Tea is the dominant flavor.
2. After the hokage duel, exchange flavors and make peace, creating a chocolate/strawberry swirl pocky sword of peace, a rabid fangirl (or schoolgirl) runs away with the pocky of peace, and the two ninja clans all run offstage after her after her.
