Nothing that simple. She will be dressed as a squire. The theme is a dragon's lair. The prop with sound is a monster box. I have a fog generator inside, plus a mechanism to bounce the lid as if there is something inside trying to escape. There's also a drill motor to twitch the dragon's tail sticking out of the side of the box.
Other props include an egg drop where a momma dragon lays plastic eggs with toys inside. Tomorrow, I have to prepare a fire. A 2-ft diameter wood disk with about 25 flickering LEDs (candle replacements). She will cover them with expanding foam from the hardware store then sprinkle some black and red paint over it.
But, thanks for the tip again. It got me back on schedule.
