Balloon goombas and koopas - oh my!

In the Super Mario games, Mario kills little brown creatures called Goombas and little green turtles called Koopas by jumping on them, which nets him coins. So how can you have a Mario party without goombas and koopas? It took surprisingly little time to repurpose the coins from last year's pirate treasure hunt INTO about 50 green and brown balloons and blow them up.

 

It took considerably LESS time for 11 delighted children to stomp them into oblivion!
