So basically we try to parody a song, and when its over, we do a new one.

I'll start.

As I walk through the grass where I catch all my pokes
I take a look inside my wallet and realize I'm pretty broke
But that's just perfect for a trainer like me
I'll beat others up, and steal their money.

Now somebody post several more lines, so on, so forth.

At 4:30 in the morning I'm grindan Jynx
your Lapras will not stand a chance against my Shinx
FOOL
And I've been training and catching so long that
EVEN A HEATRAN CAN'T DEFEAT MY BRONZONG
