Katrinka is a fictional character in the Hey Arnold! TV Series.
She is a 4th grade student at PS 118, but only used as a character to "make up the numbers" in a group of kids. Despite this, however, Katrinka is included on Rhonda's "Cool List" (where her name is spelled "Katrina") and is even seen dancing with Big Gino during the April Fool's Day dance.
