Chip Crosswire

Chip Crosswire is Muffy's college-aged older brother. He is a freshman at Tallahassee Tech, a fictional college in the series. He closely resembles his father, Ed.

He is first referred to in Arthur's Perfect Christmas, where a Christmas stocking with his name is hanging on the Crosswires' fireplace.

He was mentioned in "Phony Fern," when Muffy says he is coming home this weekend. That turns out to be the next episode, "Matchmaker, Matchbreaker," his major appearance.

He was later mentioned in "The Great MacGrady" and "Through the Looking Glasses."

Physical appearance
Chip is a monkey depicted with a pale complexion and short orange hair with bangs, and wears a blue sweater over a white shirt, gray khakis, and green shoes with gray accents.

His original design was seen in a Crosswire family portrait inside of a tent at camp on a page in Arthur Goes to Camp, first published in 1982. His original design was clumps of hair, brown monkey fur, glasses, and a suit and tie. After 27 years of absence, he was brought back, and was completely redesigned and no longer wears glasses, but still wears a suit and tie as alternate clothing.

Friends
Chip has many friends from college, but they have never been seen in the series. It is unknown to where he went to and graduated from high school, and who his friends from high school were, but he was never seen until "Matchmaker, Matchbreaker."
 * Catherine Frensky - When Chip came home from Tallahassee Tech, he and Catherine both met after he learned that Muffy and Francine are best friends together. Muffy and Francine were planning to set up him and Catherine together as a date. He and Catherine both went out on a date, and spent time together from time to time. However, the two both eventually split up and no longer dated each other; and decided that they're just friends, not lovers.
 * Lexie - In "Phony Fern," Muffy tells Fern that Chip broke up with someone named Lexie, and Lexie is now dating someone named Biff.

Trivia

 * According to "The Great MacGrady," Chip gave his father his signature pink tie.
