How to help the King blow out his candles?

Here are our ideas. 

 Wind Cannon
Austin is blowing into the Wind Cannon.
At the end of the Wind Cannon it can spread the wind to blow out the candles.  

The King's Water Machine.
It has little drops to put our the flames.  It has a water button that can make more water come out.  It has a blazing button that goes very fast.

Robot Monster
There is a little cord that you pull and air comes out of the arms and
legs to blow the candles out.
