Gomasuritchi's favorite food is sesame crackers. He says 「へぇ！アニキ！」 (Hey! Brother!) to Bikertchi sometimes as they are good friends. Gomasuritchi is very talkative and likes to flatter people, but sometimes he does it just to make them do what he wants. However, according to Kuromametchi in Corner Shop 3, he is really quiet at home.
