[Oh hello girl around his age. Shaun's face appears on the screen again as he turns it around, and goes over to a bench to sit down to talk.]

You mean you don't know about evolution yet? Little pokemon evolve into bigger and stronger ones as you raise them. Richie, my Mightyena - that is, the one who looks like a dog - is almost three times as big as she was before she evolved.

...She was a present. I dunno where you can find them in the wild. There might be breeders with eggs, though! She was a Poochyena, if that helps you find one.
