My 14 yr old son wants to offer you some "good" advice.
Tag-Slay the Dragon--"it" is a knight and trys to slay the dragons (tag), if tagged, you are now the Knight--switch off the foam sword and mask.
red light, green light-"it" is the dragon and calls out red light when facing the group and green light when turned away (quickly), the knights are sneaking up on the dragon. If you move during red light, dragon eats you up, you must go back to start. (no one is actually eaten)
Hide and Seek-Find the missing princess, don't find the dragons! "it" is a knight. (or, if he prefers BEING the dragon, switch. it is a dragon, avoid the knights!)
Have a flaming good time!
~A. (and Jeremy)
