Pebble Cement Rock

There once was a rock

Who was always tossed around

It didn't care about the beating it took

Whether it was from the ground, steel, ice, water or grass

But one day it missed its mark and landed

In the back of a cement truck

And got all covered in muck

Evolving into Graveler

Oh such luck

Even more angrier than before

You'd think for being a rock and ground type

That he wouldn't be as sturdy and less of a rock head then before

All the while still being somewhat immune to the attributes

Of grass, ground, water, fighting, ice and steel

Before finally evolving one final time and rolling on out of there

But some crashes are bound to happen here and there

Upon becoming Golem and shed your skin once a year

But sadly you're still weakened by the usual attributes

Of ground, grass, fighting, water, ice and steel

Despite still being a rock head and all the while being sturdy as hell
