I play the role of dispatch. They fight the fires! I gave the megaphone that sounds the alarm to Charlie a few times and directed him on what to say. Either way, they would laugh so hard when I would say, "Ahhh, we are done. Time for a rest!". And they would make it go off again. I'd jump up and yell, "We've got another emergency!".
And playing dress up! Here's Aiden as a pirate!
We also protected the castle (bouncy house) with our swords. We launched the balloons as cannons too.
