Character: bob (undertale)

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.

Bob is usually depicted as a male black-haired Temmie with a blue shirt.
