Pin is an ordinary mechanic and plumber, and is absolutely always ready to help his friends with any mathematical or physical problem. He is very kind, smart and attentive, and knows how to get along even with the hyperactive Krosh (which not everyone can cope with).

The man, as usual, was in his garage and was working hard on something, and music was playing on his tape recorder to make it more fun and comfortable for him to work, since Pin didn't like silence.
