He's mean.
This rock is the best. Not because of how he looks, but I can safely say because of how he talks. A talking pet rock? Now I have got to have one of those. I remember playing this so long ago and it's still a nice game to play. Infact, most gadgets are.
The best line he says was probably "Well I'm a rock. I laid down in the dirt for about 20 years, until an idiot picked me up and now I'm here." Well that's the just of what he said. I can't remember word for word.
He is not useless however. I mean he fucking talks. What more can you want out of a pet? Much less a rock. I also find it funny that we get to try to feed and water him. He's a rock. He dosn't eat anything although he does have a mouth.
One thing that did get old with him is the over use of the word moron. He uses it way to much. I also remember another funny line he said. It was about starving people in Africa and you're trying to give food to a rock. Good job dude! Maybe next time we'll get a pet plant! Or a pet house! I don't know, I'm just making up stuff now.
