Piert (I tried type Pietr (Пётр) but did it wrong) is a young guy works as a “soviet geologist” and this is not a nationality but a position. Piert has a dream to find a sasquatch one day, that is why he had become a geologist. Piert’s best friend is Arni the sasquatch who lives with him in a wooden cabin but Piert doesn't realize that Arni is a sasquatch (because Arni wears ninja mask ribbon, ninja shoes and ninja gloves).
Piert is a bit selfish, confident, talkative, loud. He likes to show-off, can be really nasty when disappointed with something. But still Piert is a good person. He always shuts the doors in a loud way, and when he does that always a picture fall from the wall.
