Rattles

Rattles is a fourth grader who is a member of the Tough Customers. He is one of the antagonists in the series. Rattles has been a member of the Tough Customers since the first season. Later in the series, he had a dog called Crusher, who first appeared in "Pet Peeved."

In the episode "Bugged" he is seen with the other kids at the playground as they are having a game of marbles. This shows Rattles does indeed hang out with other kids in the school despite being a bully.

He seems interested in knitting. For example, he is a member of Dr. Fugue's knitting club in "Arthur Unravels." Also, it is mentioned throughout the series, though more recently than before, that he is skilled at sewing.

Appearance
Rattles has a tuft of hair sticking out of his red baseball hat, which he wears backwards. He wears a black leather jacket, a whitish-yellow T-shirt, green jeans and high tops.

Species
There is much confusion as to exactly what animal Rattles is. He so rarely takes off his hat that the producers have actually changed what animal he is multiple times. In "D.W., Dancing Queen", he takes off his hat while dancing and has dog ears. This is interesting compared to "Brother Can You Spare a Clarinet?", where he sticks his earplugs into the sides of his head. Also, in an imagination scene of "Thanks a Lot, Binky," he has small ears on the top of his head, although they were hidden under a full-body cast, so they could be cat ears. When playing sports, he sometimes takes off his hat and has cat ears, such as in "Arthur the Loser", "Meek for a Week", and "Arthur Cleans Up."

Trivia

 * In the episode "The Last Tough Customer", Rattles revealed his dad is in marketing.
 * In the episode "Brain's Chess Mess", Rattles reveals he is a skilled chess player.
