Need ideas on how to run a lighthearted puppet dragon fight
Long story short, the players secured the help of a Brass Dragon to fight a very powerful threat to their city by promising a citywide party for the dragon to attend. The city is putting on a giant puppet show as party of the celebration, two massive dragon puppets that are each controlled by a team of dancers are spending the day weaving through the city and will ultimately clash at the end of the festivities in a giant acrobatic and illusory display for the citizens. Each dragon puppet, a copper and a green, have teams handing out small prizes and securing promises from the citizens to back their specific dragon if the time comes to defend the city from the other.
I'd like this to be a fun little scene where the party and citizens can have a big mock battle to determine the victor. I am at a loss as to how to actually play this out. Please, give me your suggestions for something engaging that isn't a full blown 3 hour long combat.
