A thunderous roar loudly rang out.

Jason looked deep into one of the tunnels  "I;d say we've got about ...twelve minutes until the portal closes and we can get home."

Kurt tapped his friend on the shoulder. "Except, we've got that thing guarding it."

Another roar.

"Aren't you supposed to be a knight?" Michelle asked,  before starting to pick through Kurt's backpack. "Where's your sword?" 

"Oh yeah, a wooden sword against something that breathes fire, that's a great plan." Kurt replied sarcastically. He pointed at the pink crown on Michelle's head. "Anyway, you're supposed to be a princess.  where's your wand?"

"It's a staff!" she exclaimed. "And I...left it at home." 

Jason sighed. "Guys, hate to interrupt, but we've down to seven minutes.  Let's just try to sneak past the dragon and get to the portal if any of us want to live to finish middle school."
