Larvitar are a soft green colour, with a red belly and a large horn on its head. They're tough, but they're not too much of a problem. It's the tyranitar you don't want to upset. They're about... the size of an adult man? Big and green. Big, green, and very territorial.

[ So please watch out for them. ]

Haha, good point. The mountain isn't so bad anyway once you get used to it. It's just not flat and -- simpler like the forest in a way, so people don't suggest it for first timers. That, and most people who ask questions like you haven't usually been training for two years already.
