However, in the first two seasons, Ren's tail constantly disappeared and was even docked by George Liquor in the season 2 episode 'Dog Show', while getting Ren and Stimpy both ready for an upcoming dog show (even though Stimpy is a cat) although it continued to appear afterwards in the episode, as well as episodes afterwards. Ren has a fairly long, rat-like, pink tail. Toon' Goodman of Animation World Magazine described Ren as scrawny, dyspeptic and violently psychotic, who loses his mind occasionally in a cumulative process resulting in him becoming, in Goodman's words, a 'screaming klaxon, neon-pink eyes dilating into twin novae inches above his jagged, monolithic teeth.' Andy Meisler of The New York Times described Ren as 'adventurous,' 'intelligent,' and 'emotionally brittle.'
'Ren' Höek is a scrawny ' Asthma- Hound' Chihuahua.
