"Oh!" Pinkie leapt to the side, catching Toothy on her back as the bat he was riding finally collapsed down into dream pieces, then hopped back over to her conversation with Rarity. "Yeah, we oughta just use the Elements! This is getting a little messy!"

She didn't really know how the other girls made their elements go off, or even entirely how to explain what she did when she was using hers, especially not while there was a giant fight going on. So instead, she hopped on top of her party cannon, balancing rather perilously on the barrel.

"Everything is great!
Everything is good!
I got the whole wide world in the soles of my hooves!"

What? Songs are clearly the best explanatory method.

"Everything is perfect!
It's falling into place~
I can't seem to wipe this smile off my face!
Life's a happy song, when there's someone by my side to sing along!"

She spun the cannon around in a tight circle, somehow without touching her hooves to the ground at all. Meanwhile, Lord Tubbington, seeing that his mistress and her small white friend were no longer under fire, threw himself bodily at the closest Nightmare Moon instead. It wasn't much of a leap, considering his girth, but there was an awful lot of him in the tackle.
