Well, because those are Elemental Monsters, I say Cool!!! But the little dance there...um...yeah...kinda gay 
Put it in somewhere as a "Easter Egg" though. Maybe one of those Ultra Rare Quests 
Quest:
Local Monsters in your Kingdom/Empire are holding a Dance Competition, you, my Lord, have been asked to judge this competition. Shall I say you will preside over the event Sire?
If you choose "Yes", you watch the monsters dance. You pick a "Winner", but, the other two monsters get pissed that they didn't win and they attack you and the winning monster. If you live through the battle and keep the "Winner" alive, he joins your Army 
That sounds....not so gay 
Note: No offense to any gay people. Some of my best friends have been gay. Some of my wife's friends are gay. Hell, I've even had some ex girlfriends who we Bi and or Lesbian. What people do behind closed doors is Their Business.
