Weee! Ka-Boom!

The box is singed by the first one, but Rex pats his side to encourage him. It's fine! Go nuts! A barrage of firework balls go off, quite a thundering bang, but the singe turns into scorch, turns into actually on fire! The flames themselves burn with the same dazzling array of colour as the firework blasts for a little while before they turn to normal fire.

"Interesting."

And Indrik is given a small piece of coal from Rex's pocket. He loves it, crunching away with a meep.
