Temmies resemble cats with dog ears as well as their normal ears, shoulder length black hair, and blue shirts, excluding the Temmie Shopkeeper, who has gray hair and a striped blue and yellow shirt instead.
All Temmies share an erratic manner of speech, where they often exclude letters, mix lower and upper cases, make inconsistencies, etc. There are some exceptions, however; Bob always speaks in perfect English, the Temmie Shopkeeper will speak in fluid English when the protagonist denies to sell an item she wants, and regular Temmies in-battle will speak in somewhat proper English when denied Temmie Flakes.
